- Hoist the cell-strip patterns to module level so they match the rest of
the module's regex style and aren't reparsed on every call.
- Type the markdown transform callback and the mention id walker so the
inline Callable signature is no longer an untyped Any.
- Add _HTTP_TIMEOUT_SECONDS alongside the other class-level tunables.
- Reject group_message_buffer_size <= 0 in a Pydantic field_validator
rather than silently disabling the buffer at write time.
- Mark SignalConfig.allow_from as a computed_field so it shows up in
model_dump() instead of being invisible to serialization.

split_message can break a long Signal payload into multiple JSON-RPC sends,
but the previous code attached the full textStyle list only to chunk 0.
Style ranges in later chunks were dropped, and ranges whose offsets pointed
past chunk 0's end were sent as invalid metadata against chunk 0.
Add _partition_styles, which rebases each range against the chunk it lives
in (in UTF-16 code units, matching the markdown converter) and splits
boundary-spanning ranges across the chunks they touch. Whitespace trimmed
by split_message's lstrip is skipped so offsets stay aligned.

Integrates signal-cli daemon via HTTP JSON-RPC as a nanobot channel.
Supports DMs and group chats with open/allowlist access policies,
markdown→Signal text style conversion, typing indicators, attachment
handling, group message context buffering, and automatic reconnect
with exponential backoff.
Includes unit tests for channel lifecycle, message routing, mention
detection, markdown conversion, and message splitting.
