* feat(feishu): add interactive card message parsing
Add support for parsing inbound Feishu interactive card messages.
When a user sends a card message, the text content is now extracted
and passed to the LLM for processing.
- Add extractCardText() to recursively extract text from card JSON
- Support both JSON 1.0 (legacy) and JSON 2.0 schema formats
- Handle nested elements: header, body, actions, columns
- Extract text from markdown, lark_md, and plain_text elements
- Add comprehensive unit tests for card parsing

* feat(feishu): extract and download images from interactive cards
When receiving interactive card messages, extract embedded images
(img_key, src, icon_key) and download them for LLM processing.
- Add extractCardImageKeys() to recursively extract image keys from card JSON
- Support img elements (img_key, src) and icon elements (icon_key)
- Update downloadInboundMedia() to handle MsgTypeInteractive
- Add comprehensive unit tests for image extraction
Images are downloaded and stored via MediaStore, then appended to
the message content as [image: photo] tags for LLM visibility.

* fix(feishu): simplify card parsing - pass raw JSON, only extract images
Address review feedback: text extraction cannot exhaustively handle all
card formats (i18n_elements, div.fields, etc.). Pass raw JSON to LLM
instead - same approach as MsgTypePost. Only image extraction remains
as images must be downloaded for LLM to process.
- Remove extractCardText() and helper functions
- extractContent() now returns raw JSON for MsgTypeInteractive
- Keep extractCardImageKeys() for downloading embedded images
- Update tests to expect raw JSON for interactive cards
* fix(feishu): don't append media tags to interactive card JSON
Appending media tags like "[attachment]" to raw JSON content produces
invalid JSON format. For interactive cards, the JSON already contains
image information and media refs are downloaded separately.
- Skip appendMediaTags for MsgTypeInteractive to preserve valid JSON
- Add test case for interactive card with images
* fix(feishu): filter out external URLs from card image extraction
Only Feishu-hosted image keys (img_xxx, icon_xxx) can be downloaded via
the Feishu API. External URLs in src field (https://...) should be
filtered out to avoid download failures.
- Add isFeishuImageKey() to detect Feishu-hosted keys vs external URLs
- Update extractImageKeysRecursive to skip external URLs in src field
- Add tests for external URL filtering and mixed scenarios
* feat(feishu): support downloading external images from interactive cards
Previously only Feishu-hosted images (img_key, icon_key) could be
downloaded. Now external URLs in src field are also downloaded via
HTTP and made available to the LLM.
- extractCardImageKeys now returns two slices: Feishu keys and external URLs
- Add downloadExternalImage to download images from HTTP URLs
- Update downloadInboundMedia to handle both Feishu API and HTTP downloads
- Update tests for new function signature
* fix(feishu): use HTTP client with timeout for external image downloads
Replaced http.DefaultClient with a client that has a 30-second timeout
to prevent hanging on unresponsive external URLs.

* fix(feishu): resolve lint errors for shadow and formatting
- Rename err variables to avoid shadowing in downloadExternalImage
- Fix struct field alignment in TestExtractCardImageKeys

* refactor(feishu): pass external image URLs to LLM instead of downloading
Instead of downloading external images from interactive cards, pass
the URLs directly to LLM. This reduces network overhead and lets
vision-capable models fetch images as needed.
- Remove downloadExternalImage function
- Append external URLs to card content for LLM processing
- Only download Feishu-hosted images via API

* fix(feishu): add blank line between functions for gci formatting
* fix(feishu): keep interactive card content as valid JSON
* feat(feishu): add Lark (international) support via IsLark config field
Add IsLark field to FeishuConfig to switch between Feishu and Lark
domains. Also fix domain inconsistency where WS client defaulted to
LarkBaseUrl while HTTP client used FeishuBaseUrl.

* docs: update documentation and web UI for Lark support
Add is_lark field to config example, feishu docs, i18n translations,
and web frontend form.

The Lark SDK v3's built-in token retry loop does not clear stale tokens
from cache when the server returns error 99991663 (tenant_access_token
invalid), causing all API calls to fail until the token naturally
expires (~2 hours).
- Add tokenCache struct (implementing larkcore.Cache) with
Get/Set/InvalidateAll methods and proper expired-entry cleanup
- Wire custom cache into lark.NewClient via WithTokenCache()
- Add invalidateTokenOnAuthError helper called in all API methods
- Consolidate extractImageKey/extractFileKey/extractFileName into shared
extractJSONStringField helper to reduce code duplication
- Move mentionPlaceholderRegex to package-level position after imports
- Rename feishuCfg field to config for clarity within FeishuChannel
- Replace @_user_1 heuristic with GET /open-apis/bot/v3/info API call
at startup for reliable bot @mention detection
- Fix double close on file handle in downloadResource by removing defer
and using explicit close in both success and error paths
- Add unit tests for common.go and feishu_64.go helpers (53 test cases)
- Remove stale "falls back to plain text" comment on Send
- Add empty ChatID validation in SendMedia to match Send
- Use messageID+fileKey as local filename to avoid write collisions
- Check allowlist before downloading inbound media to avoid wasted I/O
- Return errUnsupported consistently from all 32-bit stub methods
Upgrade the Feishu channel from basic text-only to full feature parity with
Telegram/Discord: interactive card messages with markdown rendering, message
editing (MessageEditor), placeholder messages (PlaceholderCapable), emoji
reactions (ReactionCapable), and inbound/outbound media support (MediaSender).
Also add @mention detection with lazy bot open_id discovery, group trigger
filtering with mention awareness, and multi-type inbound message parsing
(text, post, image, file, audio, video).
Introduce SenderInfo struct and pkg/identity package to standardize user
identification across all channels. Each channel now constructs structured
sender info (platform, platformID, canonicalID, username, displayName)
instead of ad-hoc string IDs. Allow-list matching supports all legacy
formats (numeric ID, @username, id|username) plus the new canonical
"platform:id" format. Session key resolution also handles canonical
peerIDs for backward-compatible identity link matching.
- MediaStore: use full UUID to prevent ref collisions, preserve and
expose metadata via ResolveWithMeta, include underlying OS errors
- Agent loop: populate MediaPart Type/Filename/ContentType from
MediaStore metadata so channels can dispatch media correctly
- SplitMessage: fix byte-vs-rune index mixup in code block header
parsing, remove dead candidateStr variable
- Pico auth: restrict query-param token behind AllowTokenQuery config
flag (default false) to prevent token leakage via logs/referer
- HandleMessage: replace context.TODO with caller-propagated ctx,
log PublishInbound failures instead of silently discarding
- Gateway shutdown: use fresh 15s timeout context for StopAll so
graceful shutdown is not short-circuited by the cancelled parent ctx
Add unified ShouldRespondInGroup to BaseChannel, replacing scattered
per-channel group filtering logic. Introduce GroupTriggerConfig (with
mention_only + prefixes), TypingConfig, and PlaceholderConfig types.
Migrate Discord MentionOnly, OneBot checkGroupTrigger, and LINE
hardcoded mention-only to the shared mechanism. Add group trigger
entry points for Slack, Telegram, QQ, Feishu, DingTalk, and WeCom.
Legacy config fields are preserved with automatic migration.
Add bus.Peer struct and explicit Peer/MessageID fields to InboundMessage,
replacing the implicit peer_kind/peer_id/message_id metadata convention.
- Add Peer{Kind, ID} type to pkg/bus/types.go
- Extend InboundMessage with Peer and MessageID fields
- Change BaseChannel.HandleMessage signature to accept peer and messageID
- Adapt all 12 channel implementations to pass structured peer/messageID
- Simplify agent extractPeer() to read msg.Peer directly
- extractParentPeer unchanged (parent_peer still via metadata)
