Rebased /todo command + auto-todos onto 0.5.0, addressing the review on #3.

Required changes:

1. Dropped the src/tui-data.ts / tests/tui-data.test.ts hunks — master's todowritesFromMessages + writeTimestamp already cover the timestamp-ranked read. The branch keeps the /todo command + message-log reader.
2. Message sources now use typed ctx.session.context({ sessionID }) with same-plugin storage fallback; deleted the ctx.client cast, the serverBaseUrls/serverHeaders helpers, and the node:fs import.

Cleanups folded in: joined split async lines; explicit undefined (never []) when no source has a list, keeping empty vs failed distinguishable; rebased on current master, keeping master's rewritten context hook and only adding the command registration/disposal. Also adds MAX_TODOS=100 / MAX_TODO_CONTENT_LENGTH=500 validation to normalizeTodos.

Tests: 69/69 green (master suite untouched + rewritten todo-command/auto-todos tests against the typed API).

Thanks @famewolf — I went through the rebase and pushed four fixup commits on top of 032099e (using the "edits by maintainers" flag) for the remaining items:

• d283e4c fix(auto-todos): seed every default entry and respect the list caps — the default (always: false) check ran against the list as it was being built, so only the first default entry injected; it now decides against the incoming list once. Entries over MAX_TODO_CONTENT_LENGTH are dropped and injection stops at MAX_TODOS, so the merged list can no longer bypass the caps added in 032099e (an auto-todos.json could previously push unbounded content into plugin storage and the injected context).
• 520223e fix(todo-command): distinguish a missing list from an empty one — undefined (no source has a list) is no longer collapsed into []; the command posts "No todo list found for this session." instead of "the todo list is empty". Also fixed the joined ctx.command.transform line from the rebase and a test's delivery value.
• 1cef0a4 test(todos): cover the normalizeTodos limits — the MAX_TODOS / MAX_TODO_CONTENT_LENGTH rejections had no tests.
• 01d1b8b docs: document the /todo command and auto-todos.json.

On prompt caching: the fixups touch neither the context hook, the reminder text, nor the unchanged-list skip — src/tui-data.ts, src/timing.ts and tests/plugin.test.ts are byte-identical to master, and the only src/index.ts diff remains the tool-call wrapping plus the command registration/dispose from your commit. I added an idempotence test (two identical writes with an always entry store the same list) so the skip added in #8 keeps working.

CI is green on 01d1b8b (Node 20/22); locally: 76/76 tests, typecheck and build clean.
