When the homeserver returns an error response, matrix-nio parses it
as a SyncError return value rather than raising an exception. The sync
loop only had backoff in the except handler, so SyncError caused a
tight retry loop (~489 req/s) flooding logs and hammering the
homeserver. Check the return value and sleep 5s before retry.

Three fixes for the Matrix adapter:
1. Remove RoomMessageMedia callback registration — RoomMessageImage
inherits from it, causing images to be processed twice.
2. Add event ID deduplication to both text and media handlers.
nio can fire the same event more than once; bounded deque+set
tracks the last 1000 events.
3. Cache images locally via Matrix client download. MXC URLs require
authentication, so the vision pipeline couldn't access them.
Images are now downloaded via the authenticated client and saved
to the local cache (same pattern as Telegram/Discord).

Fixes#1842
The MessageEvent dataclass expects 'reply_to_message_id' but the Matrix
connector was passing 'reply_to'. This caused replies to fail with:
MessageEvent.__init__() got an unexpected keyword argument 'reply_to'
Changed the parameter name to match the dataclass definition.
1. sms.py: Replace per-send aiohttp.ClientSession with a persistent
session created in connect() and closed in disconnect(). Each
outbound SMS no longer pays the TCP+TLS handshake cost. Falls back
to a temporary session if the persistent one isn't available.
2. matrix.py: Use proper MIME types (image/png, audio/ogg, video/mp4)
instead of bare category words (image, audio, video). The gateway's
media processing checks startswith('image/') and startswith('audio/')
so bare words caused Matrix images to skip vision enrichment and
Matrix audio to skip transcription. Now extracts the actual MIME
type from the nio event's content info when available.
Neither adapter called _mark_connected() after successful connect(),
so _running stayed False, runtime status never showed 'connected',
and /status reported them as offline even while actively processing
messages.
Add _mark_connected() calls matching the pattern used by Telegram
and DingTalk adapters.
Add support for Mattermost (self-hosted Slack alternative) and Matrix
(federated messaging protocol) as messaging platforms.
Mattermost adapter:
- REST API v4 client for posts, files, channels, typing indicators
- WebSocket listener for real-time 'posted' events with reconnect backoff
- Thread support via root_id
- File upload/download with auth-aware caching
- Dedup cache (5min TTL, 2000 entries)
- Full self-hosted instance support
Matrix adapter:
- matrix-nio AsyncClient with sync loop
- Dual auth: access token or user_id + password
- Optional E2EE via matrix-nio[e2e] (libolm)
- Thread support via m.thread (MSC3440)
- Reply support via m.in_reply_to with fallback stripping
- Media upload/download via mxc:// URLs (authenticated v1.11+ endpoint)
- Auto-join on room invite
- DM detection via m.direct account data with sync fallback
- Markdown to HTML conversion
Fixes applied over original PR #1225 by @cyb0rgk1tty:
- Mattermost: add timeout to file downloads, wrap API helpers in
try/except for network errors, download incoming files immediately
with auth headers instead of passing auth-required URLs
- Matrix: use authenticated media endpoint (/_matrix/client/v1/media/),
robust m.direct cache with sync fallback, prefer aiohttp over httpx
Install Matrix support: pip install 'hermes-agent[matrix]'
Mattermost needs no extra deps (uses aiohttp).
