Channel Formatting

This skill wires channel-aware Markdown conversion into the outbound pipeline so Claude's responses render natively on each platform — no more literal **asterisks** in WhatsApp or Telegram.

Channel	Transformation
WhatsApp	`bold` → `bold`, `italic` → `_italic_`, headings → bold, links → `text (url)`
Telegram	same as WhatsApp, but `[text](url)` links are preserved (Markdown v1 renders them natively)
Slack	same as WhatsApp, but links become `<url\|text>`
Discord	passthrough (Discord already renders Markdown)
Signal	passthrough for `parseTextStyles`; `parseSignalStyles` in `src/text-styles.ts` produces plain text + native `textStyle` ranges for use by the Signal skill

Code blocks (fenced and inline) are always protected — their content is never transformed.
