Guoguo cb1e1a3595 fix(feishu): fix image download with API fallback and post image support (#2708)
* fix(feishu): fix image download with API fallback and post image support

- Add Image.Get API fallback when MessageResource.Get fails (different
  permission scope: im:resource vs im:message:readonly)
- Extract and download images from post (rich text) messages
- Extract images from interactive card messages
- Deduplicate post image keys across locales
- Add comprehensive tests for new helpers

* feat(media): add image path tags alongside base64 for LLM file access

Images are still base64-encoded into msg.Media for multimodal LLMs,
but now also get [image:path] tags injected into message content so
the LLM knows the local file path for save/forward operations.

* refactor(media): only auto-inject images for tool results, not user messages

Channel-received images (role=user) now get path tags only, letting
the LLM decide whether to view via load_image or just operate on
the file. Tool result images (role=tool, e.g. load_image) are
base64-encoded into a synthetic user message appended after the tool
message, since many LLM APIs don't support image_url in tool messages.

* fix(media): preserve tool-message ordering for multi-tool-call scenarios

Move synthetic user message (carrying base64 tool images) to after the
entire contiguous tool-message block instead of immediately after each
tool message. This preserves the assistant→tool→tool ordering required
by OpenAI-compatible APIs.

Also fix load_image to use generic [image: photo] placeholder so
injectPathTags can properly replace it with the actual path.

* fix(test): update load_image test for [image: photo] placeholder

The test was checking ForLLM for the media:// ref, but load_image now
emits the generic [image: photo] placeholder instead.

* fix(media): match all channel image placeholders in injectPathTags

Different channels emit different placeholder formats — Telegram/Feishu
use [image: photo], WeCom/WeChat/Line use bare [image], QQ/Discord use
[image: <filename>]. The previous string-match code only handled
[image: photo], so for the other channels the path tag was appended as
a duplicate, producing content like "[image] [image:/path]".

Switch to per-type regex that matches all generic placeholder shapes
while leaving path tags ([image:/path]) untouched. Also fixes the same
issue for [audio], [video], [file] tags. Added test coverage for the
various placeholder shapes.

* fix(media): skip path tag append for JSON content (Feishu cards/posts)

When content is structured JSON (interactive cards, post messages),
injectPathTags now skips the fallback append — only placeholder
replacement is attempted. This prevents corrupting JSON payloads
like {"schema":"2.0",...} with appended [image:/path] tags.

Adds looksLikeJSON() helper and three test cases covering JSON
objects, arrays, and an end-to-end resolveMediaRefs scenario with
Feishu card content.

* fix(media): prepend path tags for JSON content, narrow looksLikeJSON

Two fixes from code review:

1. looksLikeJSON now only checks for '{' prefix (not '['), avoiding
   false positives on regular text like "[update] see attached".

2. For JSON content (Feishu cards/posts), path tags are prepended
   before the JSON instead of being silently dropped. This ensures
   the LLM can discover attached images via the path tag while the
   JSON payload stays valid for downstream parsing.

ywj 009a8d702b Feat/feishu card parsing (#1534)
* 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

Fixes #<issue_number>

* 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.

* 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
