feat(channels): add Synology Chat native channel (#23012)

Browse Source 
* feat(channels): add Synology Chat native channel

Webhook-based integration with Synology NAS Chat (DSM 7+).
Supports outgoing webhooks, incoming messages, multi-account,
DM policies, rate limiting, and input sanitization.

- HMAC-based constant-time token validation
- Configurable SSL verification (allowInsecureSsl) for self-signed NAS certs
- 54 unit tests across 5 test suites
- Follows the same ChannelPlugin pattern as LINE/Discord/Telegram

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat(synology-chat): add pairing, warnings, messaging, agent hints

- Enable media capability (file_url already supported by client)
- Add pairing.notifyApproval to message approved users
- Add security.collectWarnings for missing token/URL, insecure SSL, open DM policy
- Add messaging.normalizeTarget and targetResolver for user ID resolution
- Add directory stubs (self, listPeers, listGroups)
- Add agentPrompt.messageToolHints with Synology Chat formatting guide
- 63 tests (up from 54), all passing
