gavrielc 561a0b6217 merge: catch up with upstream main

gavrielc ccb4523a54 chore: remove direct pino/pino-pretty dependency
Pino was replaced with a built-in logger on main. For branches
with baileys (WhatsApp), pino resolves as a transitive dependency
of @whiskeysockets/baileys.

gavrielc e87d15db96 feat: channel-aware text formatting for WhatsApp, Telegram, Slack, Signal
Adds src/text-styles.ts with two zero-dependency functions:

- parseTextStyles(text, channel) — converts Claude Markdown to each
  channel's native syntax before delivery
- parseSignalStyles(text) — strips Markdown markers and returns
  plain text + SignalTextStyle[] ranges for signal-cli

Wires parseTextStyles into the outbound pipeline via formatOutbound
in router.ts and both sendMessage paths in index.ts.

Includes 73 tests in src/formatting.test.ts.
