Signal-cli sends dataMessage wrappers for profile key updates and other
metadata events that have no actual text content. These were reaching the
gateway as msg='' and triggering full agent turns for nothing.
Add early return in _handle_envelope() when both message field is empty/
missing/whitespace AND there are no attachments. Messages with media
attachments but no text still flow through.
- 12 lines added to gateway/platforms/signal.py
- 5 new tests in TestSignalContentlessEnvelope class

Saved to config.yaml and leaves the API key blank,
the old code skipped writing it entirely. This caused the uvx daemon
launcher to fail at startup because it couldn't distinguish between
"key not configured" and "explicitly blank key."
Now HINDSIGHT_LLM_API_KEY is always written to .env so the value
is either set or explicitly empty.
Cherry-picked from PR #13159 by @cdanis.
Adds native media attachment delivery to Signal via signal-cli JSON-RPC
attachments param. Signal messages with media now follow the same
early-return pattern as Telegram/Discord/Matrix — attachments are sent
only with the last chunk to avoid duplicates.
Follow-up fixes on top of the original PR:
- Moved Signal into its own early-return block above the restriction
check (matches Telegram/Discord/Matrix pattern)
- Fixed media_files being sent on every chunk in the generic loop
- Restored restriction/warning guards to simple form (Signal exits early)
- Fixed non-hermetic test writing to /tmp instead of tmp_path
