Ports the fixes from fix/osnap-circle-arc-ellipse-intersection (and
this session's audit follow-up) onto this branch. All are independent
correctness/reliability fixes, unrelated to the parametric-constraint-
system work also in progress here.
1. OSNAP Intersection snap used a tessellated approximation instead of
exact geometry (GitHub discussion #1052): a circle/arc always
tessellates at a fixed 48 segments in the resident wire set
regardless of radius or zoom, so every circle/arc intersection snap
was off by construction. Added exact_circle_intersections, a
closed-form, frame-independent circle/arc-vs-circle/arc solver,
wired into both Intersection-snap code paths ahead of the
tessellated sweep. This branch's TangentGeom predates the
PlanarEllipse variant added upstream, so the ellipse/line
generalization from the upstream fix isn't ported here — this
covers the literal reported bug (a circle-circle case) using only
variants this branch already has.
2. Unbounded MINSERT allocation: array_offsets() reserved one Vec
element per array instance with row/column counts parsed as
unchecked u16s — a corrupt 65535x65535 pair requests ~96 GiB.
Fixed with a documented instance budget (20,000), enforced at both
the load-time corrupt-entity filter and a render-graph failsafe.
3. MINSERT spacing was scaled by the block's own scale:
insert_instance_transform composed the offset translation before
the instance transform, so x/y block scale multiplied the row/
column spacing too. Fixed by orienting the offset with rotation +
OCS only, then translating the already-scaled instance transform.
4. Automation "open" skipped the finalization (block-origin
normalization, raster-path resolution, source_path) and corrupt-
entity purge a UI open always runs. Added
io::load_bytes_finalized(path, bytes), used by automation's "open"
handler, which now also reports the purge count.
5. Material maps were uploaded without checking
device.limits().max_texture_dimension_2d, unlike raster-image
rendering (which already tiles to that limit). A mesh material is
sampled by UV, so it can't use the same tiling trick — instead,
upload_rgba_texture now downscales an oversized image before
upload, falling back to the 1x1 material color if malformed.
6. Sketch-constraint persistence/undo, audit-found while reviewing
this branch's own constraint system:
- Clearing every constraint in a scope after a prior non-empty save
left the stale XRecord in place, resurrecting the deleted
constraints on the next load. materialize_sketch_constraints_for_
save now actively removes the XRecord when a scope goes back to
empty.
- ERASE removing an entity took its constraints with it (design
doc's deletion policy), but sketch_constraints lives on Scene,
outside document/document.objects, so nothing captured that
mutation for undo — the erased geometry came back on undo, but
its constraints didn't. refresh_sketch_constraints's deletion
pass now records the touched scope's before-image into the same
UndoRecording the entity removal rides in, threaded through a new
sketch_constraints channel on DeltaSnapshot, so one undo restores
both together. HistorySnapshot::Delta is now boxed (clippy
flagged the resulting size skew across undo/redo stack variants).
31 new/adapted tests across all six fixes. Full workspace suite passes
except the one pre-existing, unrelated font-test failure also present
on main.

Ports FreeCAD's planegcs 2D geometric constraint solver to Rust as a new
crates/ocs_gcs workspace member, and wires it into the document/scene model
as a persistent SketchConstraintSet: Coincident, Horizontal/Vertical,
Parallel/Perpendicular, Equal, Tangent, Distance, Angle and Radius
constraints that re-solve live (including mid-drag, not just on release),
render glyphs and a DOF badge, flag conflicts with a one-click resolver
pill, and round-trip through save/load via an XRecord blob.
Also includes docs/command_reference.md (a statically generated reference
of every registered command and its prompt sequence) and
docs/named_parameters_design.md + docs/backlog.md, which hand off the next
queued feature (a named-parameter/expression table) and consolidate every
deliberate scope-down and open gap found along the way, so a fresh session
has a complete starting point.

Handling a document-open Apple Event (a warm "Open With" while the app
is already running) silently promotes this process from
NSApplicationActivationPolicyAccessory to a normal foreground app —
confirmed with lsappinfo, not assumed: its own entry flips from
type="UIElement" to type="Foreground" the instant it handles a second
Apple Event (a cold launch's own first event doesn't trigger this).
That gave the launcher its own, contentless Dock icon sitting next to
the real editor's, both apparently "the same app" to the user but
actually two separate Dock entries.
Re-set Accessory explicitly right after relaying, in the one place
every open (cold fallback, document open, and reopen-while-running)
already funnels through.

Quitting the real GUI binary (Cmd+Q) leaves the launcher itself still
running — that's by design, so it can keep relaying opens for the
session. But reopening the app afterward (Dock icon, double-clicking
it in Finder again) reactivates that same long-lived launcher process
rather than triggering a fresh cold launch, since Launch Services
still considers the bundle running. Neither of the delegate methods
already handled covered that: applicationDidFinishLaunching: only
fires once, at the launcher's own original cold start, and
application:openURLs: only fires when a document was named. The net
effect: the Dock icon would appear, but no window ever showed.
applicationShouldHandleReopen:hasVisibleWindows: is exactly the
callback AppKit fires for this reactivation case. Reproduced and
verified the fix against the real sequence (cold launch, kill only the
GUI process to simulate Cmd+Q, reopen) rather than assuming it from
the delegate method's docs alone.

The previous commit's Apple Event handler only ever catches an open
sent to an already-running process. A cold double-click (app not
running yet) still failed: every registration point tried inside the
real binary — before app::run(), on the Subscription's first poll,
even the literal first statement of main() — reliably caught a warm
open but never the original cold-launch event. A raw
AEInstallEventHandler in a separate, minimal, non-AppKit process (no
winit/iced, just a manual CFRunLoopRunInMode pump) still missed it
too, ruling out "the real binary's heavy dependency graph loading
before main() wins the race" as the explanation.
What does reliably catch a cold launch, verified against real
Finder-equivalent opens: a from-scratch NSApplication with its own
delegate implementing application:openURLs: — in a process where we
own setDelegate: from the start, with no contention over the single
delegate slot winit already claims. That has to be a separate process
from the real GUI binary (only one -[NSApplication run] call can own a
process), so src/bin/ocs_launcher.rs is now the .app's actual
CFBundleExecutable: a small, dependency-light binary (no iced, wgpu,
or cadkernel) whose only job is to catch the open and relay it.
Relaying by replacing this process's image (exec, same PID) or by
spawning a child and exiting turned out to both be dead ends: Launch
Services tracks "the running instance of this bundle" by the
Application Serial Number it handed out to whichever process it
actually launched — this launcher, not whatever it execs into or
spawns. Once the launcher's own ASN stopped pointing at a live,
listening process, every later open Finder tried to deliver silently
went nowhere (measured with lsappinfo against a real second "Open
With", not assumed). So the launcher now stays running for the app's
session — invisible, via NSApplicationActivationPolicyAccessory, since
it owns no window — and relays every open (cold or warm) over the same
channel a second CLI invocation already uses: io::single_instance.
That relay only worked once single_instance's rendezvous key stopped
being computed from the running executable's own path. That was fine
when one binary always did the job, but the launcher and the real
binary are different executables and independently computed different
ports, so they could never find each other. Anchor the key on the
enclosing .app bundle instead, shared by both.
packaging/build_macos_signed.sh and .github/workflows/release.yml now
build ocs_launcher and place it at Contents/MacOS/OpenCADStudio (the
CFBundleExecutable Info.plist already names), with the real GUI binary
renamed to Contents/MacOS/OpenCADStudio-App alongside it.

Double-click / "Open With" never puts the file on argv — Finder always
delivers it as a kAEOpenDocuments Apple Event instead, which nothing in
this app listened for, so it just showed "cannot open files in this
format" even though the file association itself was registered
correctly.
The standard fix, implementing application:openURLs: on this app's own
NSApplicationDelegate, isn't available here: winit already installs
its own delegate to own window/lifecycle events, NSApplication has
exactly one delegate slot, and winit's class doesn't implement the
open-document method.
This bypasses the delegate protocol and registers directly with the
lower-level Apple Event Manager (AEInstallEventHandler) instead — the
same mechanism AppKit's delegate forwarding is itself built on, and
independent of who owns the delegate. Registration happens on the
iced Subscription's first poll rather than in main() before app::run()
— registering earlier gets silently overwritten by winit's own
NSApplication startup, confirmed by testing against a real `open -a`
rather than assumed from Apple's docs.
This handles a file opened while the app is already running. A cold
launch (app not running yet) needs a different mechanism, in the
following commit.
