Replaces AutojoinRoomsMixin (whose /joined_rooms scan 404s against Continuwuity) with a lightweight room.invite handler. Fixes the bot silently failing to start after the claude-bot token switch.

Replace AutojoinRoomsMixin with a lightweight invite handler fc53251285

Same root cause as the earlier whoami fix: the mixin's initial
/joined_rooms scan 404s against Continuwuity even though the endpoint
works fine when called directly. Only auto-join-on-invite was actually
needed, so a plain room.invite listener replaces the whole mixin.

Review summary

Correctness — likely doesn't fix the bug (high confidence, verified against the installed library source):

agent/src/matrixBot.js:47-60 — The PR's premise is that AutojoinRoomsMixin does a /joined_rooms "scan" on startup that 404s against Continuwuity. I checked the installed matrix-bot-sdk@0.7.1 source directly:

AutojoinRoomsMixin.setupOnClient(client) (lib/mixins/AutojoinRoomsMixin.js) is literally just client.on("room.invite", (roomId, inviteEvent) => client.joinRoom(roomId)) — no scan, no /joined_rooms call.
The actual /joined_rooms call — this.lastJoinedRoomIds = await this.getJoinedRooms() — lives inside MatrixClient.start() itself (lib/MatrixClient.js:559), unconditionally, regardless of whether the mixin is registered. It's followed immediately by await this.getUserId(), which hits /account/whoami — the same endpoint the earlier commit (58bce82) already identified as 404ing on Continuwuity.

Since startMatrixBot() still calls await client.start() (line 99), and doRequest rejects on non-2xx, this call will still throw before the sync loop (and the new room.invite handler) ever runs. The new hand-rolled invite handler is functionally almost identical to what the mixin already did — it just replaces one client.on("room.invite", ...) registration with another, wrapped in try/catch. That doesn't touch the code path that's actually failing.

Recommend verifying against the real Continuwuity error logs which endpoint(s) actually 404 before concluding this is fixed — it may need to skip/replace the getJoinedRooms()/getUserId() calls inside start() itself (similar to how 58bce82 worked around the direct getUserId() call).

Everything else (try/catch around joinRoom, README additions) looks fine and unrelated to the bug.
