Salvage of PR #41284 onto current main. Relocates the last 9 inline messaging
adapters (+ satellites: telegram_network, feishu_comment/_rules/meeting_invite,
wecom_crypto, wecom_callback) from gateway/platforms/ into self-contained
bundled plugins under plugins/platforms/<x>/, discovered via the platform
registry. Strips the per-platform core touchpoints from gateway/run.py,
gateway/config.py, hermes_cli/gateway.py, hermes_cli/setup.py, and
tools/send_message_tool.py.
Carries forward the migration fixes (explicit enabled:false honored,
get_connected_platforms forces discovery, plugin is_connected via
gateway.get_env_value, logs --component gateway matches plugins.platforms.*,
matrix hidden on Windows).
Additionally ports config keys main added since the PR base: the matrix
plugin's _apply_yaml_config now also covers allowed_users,
ignore_user_patterns, process_notices, and session_scope (the inline
gateway/config.py matrix block gained these in the 1340 commits the PR sat
open; they would otherwise have been silently dropped on deletion).
* fix(matrix): isolate room context and inbound dispatch
* test(matrix): cover room isolation and dispatch regressions
* docs(matrix): document room isolation and session scope
* fix(matrix): stabilize CI requirement checks
* test(matrix): isolate mautrix stubs in requirements tests
* fix(matrix): port room-scoped status and resume to slash commands mixin
Move Matrix /status scope output and /resume same-room guards from the
pre-refactor gateway/run.py into gateway/slash_commands.py so PR #18505
foundation behavior survives the upstream god-file decomposition.
Uses i18n keys for Matrix resume/status messages. Preserves upstream
session.py fixes (role_authorized, DM user_id isolation).
* docs(matrix): explain inbound dispatch via handle_sync loop
Document why Hermes uses an explicit sync loop with handle_sync() rather than
client.start(), aligning with upstream #7914 diagnostics while preserving
Hermes background maintenance tasks.
* fix(i18n): add Matrix resume/status keys to all locale catalogs
The Matrix /resume and /status slash-command keys added in the foundation
PR must exist in every supported locale file. tests/agent/test_i18n.py
asserts key and placeholder parity across catalogs.
Non-English locales use English strings as interim placeholders until
community translators can localize them.
* fix(matrix): restore gateway authz for allowed_users; honor config require_mention
Revert the early MATRIX_ALLOWED_USERS gate in _on_room_message so inbound
sender authorization stays in gateway authz like main. Parse require_mention
from config.extra (platforms.matrix / top-level matrix yaml) with env fallback,
matching thread_require_mention and fixing Forge when require_mention is set
only in profile config.yaml.
* fix(matrix): harden status scope and allowlisted DMs
* fix(matrix): use session store lookup for resume scope
