refactor(coding-agent/slash-commands): removed collab qrcode slash commands

- Removed qrcode and qrcode-view subcommands from the collab command.
- Updated showCollabLink to always trigger QR code display.
- Refactored internal verb logic to simplify session sharing flow.

 The browser line is click-to-join (an OSC 8 hyperlink to the full `https://` deep link): the relay serves the web guest client at `/`, and the room id + key ride in the URL fragment. From another omp (any directory, any machine), either form works:

+Running `/collab` or `/collab view` starts or displays the active hosting session, rendering both the terminal/browser join links and their corresponding QR codes.

 ### Added
 
 - Updated the `pi` option of the `tools.format` setting to use the new compact sigil-delimited owned tool-calling dialect (`§`/`«…»`/`¤`/`‡‡`) that uses ~46% fewer tokens than the legacy format on typical calls.
-- Added `/collab qrcode` and `/collab qrcode-view` one-shot terminal QR output for browser join links and a `collab.webUrl` setting for separately hosted collab web clients.
+- Integrated terminal QR codes directly into `/collab` and `/collab view` to display both deep links and scannable codes, and added a `collab.webUrl` setting for separately hosted collab web clients.
