feat(memory): carry bot-owned notes across chats

[leoisadev1]

Bots need small, editable notes that carry useful context into later chats. This replaces saved facts with bot-owned USER.md and MEMORY.md files and separate GROUP.md notes for each group. Chat observations remain separate.

Memory is supplied on every turn, with enforced file limits and a review after ten successful prompts in each private or group scope. Recent context now keeps 30 complete turns within a roughly 64,000-token budget, retaining messages that observations have not covered. Web and mobile memory editors support direct changes, and archive import/export preserves notes and observations. Approved legacy facts migrate once; unsupported or overflowing facts remain in an archive.

The final fixes bound hand-edited prompt context, reject stale saves and changed bot ownership, reject cross-chat archive restores, and preserve pending observations. Failed imports roll back file and observation changes; queued observation writes cannot be erased by a stale restore. Failed lock initialization releases its handle and lock before retry.

Verified with 442 focused tests, server/web/mobile/contracts/client-runtime typechecks, targeted lint, browser save/reload/clear and archive round-trip, and real GPT-5.6 Sol conversations. The live cadence test completed ten prompts and verified one successful review call on turn eleven. Automated-review fixes passed 208 focused tests, including real LibSQL restore failure and stale-preview cases, plus browser stale-save rejection and archive restoration. Native mobile device execution and live calls through other providers were not tested. Desktop uses the shared web renderer; no Electron shell behavior changed.
