Three improvements to the WhatsApp Baileys bridge:
1. Forwarded message detection: Extracts contextInfo.isForwarded from
all message types (text, image, video, audio, document) and passes
it as isForwarded in the InboundMessage. Allows the agent to
distinguish forwarded content from direct messages — useful for
different handling (e.g., transcribe-only vs execute as instruction).
2. Startup timestamp guard: Records the timestamp when the bridge
starts and drops any messages with messageTimestamp older than
startup time. Prevents replaying message history on reconnect,
which caused duplicate processing and stale command execution.
3. Contact message handling: Adds support for contactMessage and
contactsArrayMessage types, extracting displayName and vcard
data instead of silently dropping shared contacts.
Changes:
- Add isForwarded field to InboundMessage interface
- Add startupTimestamp guard in message processing loop
- Add contactMessage/contactsArrayMessage extraction
- Extract contextInfo.isForwarded from all media message types
Keep the channel enhancements aligned with the current codebase while preserving a simpler product surface. This keeps QQ, Feishu, Telegram, and WhatsApp improvements together, removes the extra Telegram-only tool hint toggle, and makes WhatsApp mention-only groups actually work.
