* fix(telegram): validate photo dimensions before sendPhoto
Prevents PHOTO_INVALID_DIMENSIONS errors by checking image dimensions
against Telegram Bot API requirements before calling sendPhoto.
If dimensions exceed limits (width + height > 10,000px), automatically
falls back to sending as document instead of crashing with 400 error.
Tested in production (openclaw 2026.3.13) where this error occurred:
[telegram] tool reply failed: GrammyError: Call to 'sendPhoto' failed!
(400: Bad Request: PHOTO_INVALID_DIMENSIONS)
Uses existing sharp dependency to read image metadata. Gracefully
degrades if sharp fails (lets Telegram handle validation, backward
compatible behavior).
Closes: #XXXXX (will reference OpenClaw issue if one exists)
* fix(telegram): validate photo aspect ratio
* refactor: use shared telegram image metadata
* fix: fail closed on telegram image metadata
* fix: preflight invalid telegram photos (#52545) (thanks @hnshah)

* fix(telegram): improve error messages for 403 bot not member errors
- Detect 403 'bot is not a member' errors specifically
- Provide actionable guidance for users to fix the issue
- Fixes#48273 where outbound sendMessage fails with 403
Root cause:
When a Telegram bot tries to send a message to a channel/group it's not
a member of, the API returns 403 'bot is not a member of the channel chat'.
The error message was not clear about how to fix this.
Fix:
1. Detect 403 errors in wrapTelegramChatNotFoundError
2. Provide clear error message explaining the issue
3. Suggest adding the bot to the channel/group
* fix(telegram): fix regex precedence for 403 error detection
- Group alternatives correctly: /403.*(bot.*not.*member|bot was blocked)/i
- Require 403 for both alternatives (previously bot.*blocked matched any error)
- Update error message to cover both scenarios
- Fixes Greptile review feedback
* fix(telegram): correct regex alternation precedence for 403 errors
- Fix: /403.*(bot.*not.*member|bot was blocked)/ → /403.*(bot.*not.*member|bot.*blocked)/
- Ensures 403 requirement applies to both alternatives
- Fixes Greptile review comment on PR #48650
* fix(telegram): add 'bot was kicked' to 403 error regex and message
* fix(telegram): preserve membership delivery errors
* fix: improve Telegram 403 membership delivery errors (#53635) (thanks @w-sss)
