* perf(app): optimize wrapped measurements and checkpoint native layout experiment
Compute full grapheme geometry only for final wrap fragments. Preserve shaped-text search behavior while bounding additive wrap probes. Keep the Android background layout experiment isolated from the normal diff renderer; native renderer integration and iOS bindings remain unfinished.
* perf(server): reduce cold diff generation work
Keep active diff reads owned across invalidation and wait for the initial watcher inventory before cold generation. Batch patch and blob reads while preserving per-file size isolation, bounded output, and daemon responsiveness. Avoid constructing fallback tokens when full-file highlighting already covers both sides.
* test(server): exercise oversized highlighted diff rejection
The single-line fixture now bypasses highlighting under the long-line guard, so it no longer reaches the structured payload limit. Use short dense lines to keep testing oversized rejection and continued socket usability.
* fix(server): queue fresh diffs for forced reads
A forced request following a repository mutation must not reuse an older active build. Invalidate that result and coalesce waiting callers onto one subsequent build. Give the cache a named object input and completed-value type.
* test(server): share deferred diff loader setup
* test(server): name completed diff cache setup
* refactor(server): use aliases for new diff imports
* fix(server): keep shipped diff imports resolvable by Node
The TypeScript build preserves path aliases without a runtime resolver. Restore relative imports for shipped code and declarations, and correct the server import guideline that prompted the regression.
Make provider catalogs compact and content-addressed so repeat launches can reuse the persisted snapshot instead of transferring it again. Remove eager global catalog loading and the stopped-agent defensive tail fetch, while keeping sequence-gap and reconnect recovery as the correctness paths. Add an opt-in production-ID Android profiling build for local startup traces.
