The once_lock_eliminates_allocation_after_first_call test from PR #257
is a timing microbenchmark that Box::leaks ~400k strings by design to
defeat allocator reuse. Mark it #[ignore] so it stays out of the default
suite; cache correctness is already covered by the pointer-identity test.

Change CadModule::ribbon_groups() from -> Vec<RibbonGroup> to -> &[RibbonGroup],
backed by a per-module OnceLock cache. The ribbon group tree is static data
(&'static str, Copy enums) that was being fully reconstructed — Vecs, String
clones, enum discriminants — on every call, including all three per-frame
call sites (view(), dropdown_overlay(), style_combo_overlay()).
- 7 built-in modules + 2 plugin templates cache via function-local OnceLock.
Safe because each is a unit struct with exactly one instance per process
(plugins run in isolated child processes; see PluginProcess::spawn()).
- SharedCadModule avoids the static pattern entirely, storing groups in an
instance field (owned.rs).
- IPC runner converts &RibbonGroup -> OwnedRibbonGroup directly via new
From<&T> impls, avoiding an intermediate clone.
- render_small/render_large and the two make_tool_row closures now borrow
(&RibbonItem, &[ToolDef]) instead of taking ownership, so the view loop
doesn't need to clone items to satisfy the old by-value signatures.
- Various match-ergonomics deref fixes (*id, *default, *icon, etc.) from
the &RibbonItem pattern change.
Add-ons had no way to request a file picker — only the host's own Open
dialog. PluginFileDialog lets a plugin tool ask the host to open a native
picker; on selection the host dispatches "<command> <path>" back to the
plugin with original case preserved (bypassing the command-line
upper-casing that mangles case-sensitive paths on Linux/macOS). The demo
plugin gains an Import tool exercising it.
Part of the #100 extensibility epic (surfaced in #106).

Move the dependency-free, semver-versioned half of the plugin contract into a
standalone workspace crate `crates/ocs_plugin_api`:
- manifest types: PluginManifest, ApiVersion, API_VERSION
- ribbon vocabulary: CadModule trait + ToolDef/RibbonGroup/RibbonItem/IconKind/
ModuleEvent/StyleKey
The host re-exports them from `crate::plugin::manifest` and `crate::modules`, so
every existing call site is unchanged. The acadrust-typed runtime surface
(HostSession) stays in the host binary; lifting it behind a HostApi trait in the
same crate is the remaining phase-1b step.
Part of #100. Docs updated in docs/plugin-architecture.md.
