* Viewport: keep the model scene in blocks and upload only what changed
Every change rebuilt the whole model scene (every body's triangles and edges) and
uploaded all of it again, so a design an agent builds one body at a time paid for the
whole model on every command. The scene is now built in blocks of a few bodies, cut
where a body's own key says, and each block's bytes and GPU buffers are kept while the
block comes back unchanged. Body boxes (fit, picking, ground shadow) are kept per mesh.
Rendering is unchanged: the bicycle from bench-agent opens to a byte-identical
screenshot.

* Browser: find an occurrence's placed bodies by name, not by search per row
Each body row of a placed component searched the placement's bodies for its own, every
frame: quadratic in the component's bodies (720 for the bench-agent bicycle's hardware).

The reader converts each item once, but every instance made its own display mesh
(tessellation, seam and tangent flags), the most expensive step of opening a large
assembly. A later instance of an item now shows its first instance's mesh, placed by
the difference of the two placements. Only rigid placements share; split lines and
any operation drop the link. Measurements and export read each instance's own
geometry, so eval output is unchanged.
Generated assemblies: mesh phase 2,215 -> 139 ms (901 bodies) and 1,028 -> 85 ms
(5,401 bodies), with the same triangle counts.

A design built over MCP is many small commands, and each one did work over the
whole design, so building or showing a 1,300-body design took minutes:
- moved components were transformed and meshed again after every change; world_state
now reuses each placed body whose definition and placement are unchanged
- next_d_name searched the design once per candidate number
- Document::eval evaluated every parameter for every expression; now only when the
expression names one
- param_rows' used_by was quadratic; the desktop no longer gathers completions on every
change while no text box has focus
solidcraft-cli bench-agent builds a generated ~1,300-body bicycle command by command
and times it (241 s -> 16 s here). Eval output is unchanged apart from timings.

A cut or an intersection between prisms (a plate and the tools through it) is now decided in 2D before either operand is meshed. A body's size and volume are measured once, a placement reads its orientation from its matrix, the evaluation cache is bounded to 64 MiB, and STEP import copies fewer shells. Hole plates evaluate 20-30% faster with less memory, and models are unchanged.

A save with cache: true also stores a small bounded PNG thumbnail (240 × 150, at most 256 KiB, keyed to the exact document) made from cached meshes only. Home uses it when its local picture is missing, without rebuilding the design; ordinary saves and downloads still omit it. Closes#303.

Refs #303. file.save / file.save_as can store a warm native geometry cache (cache: true, off by default) keyed to the document hash, app version and adapter revision. Opening shows a bounded preview from it until the rebuilt session replaces it. Any cache failure counts as a miss.
* feat(sketch): constructive solving ahead of the numeric solver
Part 1 of splitting #251: the sketch crate only. A graph-constructive front
end (Owen 1991; Fudos & Hoffmann 1997) places what it can by ruler-and-compass
loci and cluster decomposition, Levenberg-Marquardt finishes and verifies the
rest, and the rank analysis stays authoritative for degrees of freedom. Solves
can follow a reference (the previous solution), so edits and drags keep their
branch instead of flipping.
New API: solve_with (hold, reference, analysis, budget) and
solve_after_value_edit; solve and solve_holding keep their signatures as
wrappers, so no caller changes here.
When the seed moves an arc's centre, the arc's unconstructed ends start carried
along (the arc translates) instead of left behind for LM to turn; found by the
reference test 20-slot-constrained.

* feat(doc): keep a sketch's solved state across value edits
Part 2 of splitting #251 (builds on part 1, the sketch crate):
- Sketch edits solve for the document's values continuing from the stored
solved state (Document::solve_sketch), so a dimension edit keeps the
sketch's branch instead of re-solving from scratch.
- A value edit (parameters, a configuration, the units) that would make a
sketch that solved before fail or turn over is refused with the
conflicting constraints named; otherwise the solved sketches are written
back into the document (Model::adopt_solved_sketches), which changes what
saved designs store.
- Later features are keyed by a sketch's solved geometry (to a 1e-6 mm
quantum), so setting a value back reuses their earlier results.
- Solved sketches in a model state are shared (Arc) between states.

* feat(sketch): live drag that keeps its solution, ended by sketch.drag_end
Part 3 of splitting #251 (builds on part 2):
- sketch.drag follows a long move in short held steps, so the geometry keeps
its branch, and reports how far it got (reached, at).
- live: true runs one frame of an interactive drag: the sketch is solved
once and shown, later features keep their last result (marked stale)
until sketch.drag_end or any command that reads the model evaluates it
(CommandSpec::live, reads_model, doc_only).
- sketch.drag_end adds the constraint the drag let go on and evaluates the
model once.
- Undo and redo evaluate a new document once (execute does) instead of
twice.
- The viewport drives drags through live frames and drag_end; dimension
text drags start only off sketch geometry.
