Absorbs battle-tested knowledge from the v2 skill into the upstream
add-signal: registration paths (new number + linked device), CAPTCHA
flow, VoIP SMS-first timing, Java prereq, config-lock warning, wiring
SQL for groups, not_member silent-drop fix, GroupV2 groupId extraction
note, and UUID-based platform ID format.
Corrects a factual error in the upstream: DM platform IDs are
signal:{UUID} (ACI), not phone numbers.
Removes the now-redundant add-signal-v2 skill.

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.

Native Signal adapter using signal-cli TCP JSON-RPC daemon. No Chat SDK
bridge or npm dependencies — uses only Node.js builtins.
Features:
- DM and group message support
- Voice message detection (placeholder text; transcription via
/add-voice-transcription skill)
- Typing indicators (DMs only)
- Mention detection via text match
- Managed daemon lifecycle (auto-start/stop signal-cli)
- Echo suppression for outbound messages
Also fixes init-first-agent.ts to skip channel-prefixing for phone
numbers (+...) and Signal group IDs (group:...), which are native
platform IDs that adapters send without a channel prefix.
Install via /add-signal skill. Uses /init-first-agent for channel wiring.
