Adds Google Chat as a new gateway platform, shipped under plugins/platforms/google_chat/ following the canonical bundled-plugin pattern (Teams, IRC). Rewired from the original PR #18425 to use the new env_enablement_fn + cron_deliver_env_var plugin interfaces landed in the preceding commit, so the adapter touches ZERO core files. What it does: - Inbound DM + group messages via Cloud Pub/Sub pull subscription (no public URL needed), with attachments (PDFs, images, audio, video) downloaded through an SSRF-guarded Google-host allowlist. - Outbound text replies with the 'Hermes is thinking…' patch-in-place pattern — no tombstones. - Native file attachment delivery via per-user OAuth. Google Chat's media.upload endpoint rejects service-account auth, so each user runs /setup-files once in their own DM to grant chat.messages.create for themselves; the adapter then uploads as them. Tokens stored per email at ~/.hermes/google_chat_user_tokens/<email>.json. - Thread isolation: side-threads get isolated sessions, top-level DM messages share one continuous session. Persistent thread-count store survives gateway restart. - Supervisor reconnect with exponential backoff. - Multi-user out of the box. How it plugs in (no core edits): - env_enablement_fn seeds PlatformConfig.extra with project_id, subscription_name, service_account_json, and the home_channel dict (which the core hook turns into a HomeChannel dataclass). Reads GOOGLE_CHAT_PROJECT_ID (falls back to GOOGLE_CLOUD_PROJECT), GOOGLE_CHAT_SUBSCRIPTION_NAME (falls back to GOOGLE_CHAT_SUBSCRIPTION), GOOGLE_CHAT_SERVICE_ACCOUNT_JSON (falls back to GOOGLE_APPLICATION_CREDENTIALS), GOOGLE_CHAT_HOME_CHANNEL. - cron_deliver_env_var='GOOGLE_CHAT_HOME_CHANNEL' gets cron delivery for free — cron/scheduler.py consults the platform registry for any name not in its hardcoded built-in sets. - plugin.yaml's rich requires_env / optional_env blocks auto-populate OPTIONAL_ENV_VARS via the new hermes_cli/config.py injector, so 'hermes config' UI surfaces them with description / url / prompt / password metadata. - Module-level Platform('google_chat') call in adapter.py triggers the Platform._missing_() registration so Platform.GOOGLE_CHAT attribute access works without an enum entry. Distribution: ships inside the existing hermes-agent package. Users opt in via 'pip install hermes-agent[google_chat]' and follow the 8-step GCP walkthrough at website/docs/user-guide/messaging/google_chat.md. Test coverage: 153 tests in tests/gateway/test_google_chat.py, all passing. Spans platform registration, env config loading, Pub/Sub envelope routing, outbound send + chunking + typing patch-in-place, attachment send paths, SSRF guard, thread/session model, supervisor reconnect, authorization, per-user OAuth, and the new plugin-registry cron delivery wiring. Credit: adapter + OAuth + tests + docs authored by @donramon77 (PR #18425). Rewire onto the new plugin hooks + salvage commit by Teknium.
