Correctness fixes:
- parseSignalStyles now uses a recursive walker so nested styles (e.g.
**bold with `code` inside**) produce correct offsets against the final
plain text. Previous impl recorded styles against intermediate text and
didn't reindex when later passes stripped prefix characters.
- *single-asterisk* maps to ITALIC (was BOLD, divergent from standard
Markdown). _underscore_ also maps to ITALIC.
- EchoCache keys on (platformId, text) so an outbound "hi" to Alice no
longer drops a real "hi" inbound from Bob.
- On TCP socket close, flip adapter connected=false and log a warning so
operators see lost daemon connections instead of silently failing sends.
- signalTcpCheck clears its 5s timeout on success so successful checks
don't leak a setTimeout handle.
Config hygiene:
- Rename SIGNAL_HTTP_HOST/PORT to SIGNAL_TCP_HOST/PORT (transport is TCP
JSON-RPC, not HTTP) and add SIGNAL_CLI_PATH for non-PATH installs.
- Remove unused readFileSync import.
- Log a warning in deliver() when outbound files are dropped (native
adapter doesn't forward attachments to signal-cli yet).
Tests:
- Nested style offset correctness
- *italic* and _italic_ ITALIC mapping
- Cross-recipient echo isolation
- Same-recipient echo still suppressed
- isConnected() flips on socket close
- Outbound-files warn-and-drop path
SKILL.md realigned to the add-telegram / add-whatsapp template: fetches
from the `channels` branch (not a `skill/*` branch), lists pre-flight
idempotency checks, adds Features / Troubleshooting sections. Added
VERIFY.md and REMOVE.md siblings.
