* feat(channels): add Slack channel via Socket Mode (#37) Implement Slack integration using Socket Mode (xapp-/xoxb- tokens): - Event-driven messaging via app_mention + message events - Policy checks: open, pairing, allowlist, disabled (DM + group) - Thread participation with configurable TTL - Markdown-to-mrkdwn formatting pipeline - Streaming support (edit-in-place + native ChatStreamer) - SSRF-protected file downloads - Debounce, dedup, reactions, group history context - 170 unit tests (format, helpers, stream, SSRF) Fix BaseChannel.HandleMessage allowlist to also check chatID, enabling group allowlist with channel IDs across all channels. Closes #37 * feat(slack): add file/media support and edit-to-mention handling - Wire inbound file download into handleMessage (images, audio, documents) - Add media.go with resolveMedia, classifyMime, buildMediaTags - Extract shared ExtractDocumentContent to channels/media_utils.go (DRY with Telegram) - Support file_share and message_changed subtypes - Handle edit-to-mention: respond when user edits old message to add @bot - Add MediaMaxBytes config field (default 20MB) - Fix debounce media accumulation (was silently dropping files) - Add 60s HTTP client timeout on file downloads - Refactor downloadFile signature for slack.File compatibility
