Adds MATTERMOST_REQUIRE_MENTION and MATTERMOST_FREE_RESPONSE_CHANNELS
env vars, matching Discord's existing mention gating pattern.
- MATTERMOST_REQUIRE_MENTION=false: respond to all channel messages
- MATTERMOST_FREE_RESPONSE_CHANNELS=id1,id2: specific channels where
bot responds without @mention even when require_mention is true
- DMs always respond regardless of mention settings
- @mention is now stripped from message text (clean agent input)
7 new tests for mention gating, free-response channels, DM bypass,
and mention stripping. Updated existing test for mention stripping.
Docs: updated mattermost.md with Mention Behavior section,
environment-variables.md with new vars, config.py with metadata.
* fix(gateway): add media download retry to Mattermost, Slack, and base cache
Media downloads on Mattermost and Slack fail permanently on transient
errors (timeouts, 429 rate limits, 5xx server errors). Telegram and
WhatsApp already have retry logic, but these platforms had single-attempt
downloads with hardcoded 30s timeouts.
Changes:
- base.py cache_image_from_url: add retry with exponential backoff
(covers Signal and any platform using the shared cache helper)
- mattermost.py _send_media_url: retry on 429/5xx/timeout (3 attempts)
- slack.py _download_slack_file: retry on timeout/5xx (3 attempts)
- slack.py _download_slack_file_bytes: same retry pattern
* test: add tests for media download retry

Add timeout=30 to all bare ClientSession, IMAP4_SSL, smtplib.SMTP, and
ws_connect calls that previously had no timeout, preventing indefinite
hangs when an external server is slow or unresponsive.
Adapters hardened:
- HomeAssistant: REST + WS session creation, ws_connect handshake
- Email: all IMAP4_SSL (x2) and smtplib.SMTP (x3) calls
- Mattermost: session creation, _api_get, _api_post, _upload_file (60s)
- SMS: session creation in connect() + fallback session in send()
Salvaged from PRs #3161, #3168, #3170 (memosr) and #3201 (binhnt92).
SMS fallback ClientSession on send() also patched (missed in #3201).

The Mattermost adapter now only responds to messages in channels and
groups when the bot is @-mentioned. DMs are always processed without
filtering.
Detection checks both the bot's @username and user ID in the message
text, providing a reliable fallback when the structured mentions field
is unavailable.
Fixes#2174
Bare strings like "image", "audio", "document" were appended to
media_types, but downstream run.py checks mtype.startswith("image/")
and mtype.startswith("audio/"), which never matched. This caused all
Mattermost file attachments to be silently dropped from vision/STT
processing. Use the actual MIME type from file_info instead.
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).
