Restructure to match the @mac-sync sister-app convention + operator direction:
- Backend service -> repo root (root package = the app); engine is CORE source,
now src/engine/ (not a separate package); imports rewritten to relative.
- MCP server -> @packages/mcp-prospector/ (agent interface; thin REST wrapper so
the coworker can trial this backend and fall back to legacy quinn-prospector).
- web/ stays a top-level surface.
- draft_engine default 'claude:sonnet' -> 'pastebin': the whole point is to run
OFF hosted Claude (which refuses adult-services copy) on OSS-uncensored LLMs on
raw GPU droplets; generative target is 'gpu:<model>'. Reuse LPv2's existing DO
GPU provisioning, not model-boss.
- docs/features/mcp.md: how the MCP works + the coworker graceful-switch protocol.
- .gitignore: ignore Swift .build/.
Verified: tsc clean, 101 tests (92 engine + 9 runner), app boots from root,
mcp-prospector builds + boots, smoke tests green (scam held, settings=pastebin).
