v2: channel isolation model, manage-channels skill, refactored channel skills

- Add three-level isolation model (shared session, same agent, separate agent)
  with agent-shared session mode for cross-channel shared sessions
- Create /manage-channels skill for wiring channels to agent groups
- Refactor all 12 v2 channel skills: lean SKILL.md + VERIFY.md + REMOVE.md
  with structured Channel Info section for platform-specific metadata
- Create /add-discord-v2 skill (was missing)
- Add step 5a to setup SKILL.md invoking /manage-channels after channel install
- Update setup/verify.ts to check all 12 channel token types
- Add docs/v2-isolation-model.md explaining the isolation model
- Update v2-checklist.md and v2-setup-wiring.md to reflect completed work

+- **type**: `webex`
+- **terminology**: Webex has "spaces." A space can be a group conversation or a 1:1 direct message with the bot.
+- **how-to-find-id**: Open the space in Webex, click the space name > Settings — the Space ID is listed there. Or use the Webex API (`GET /rooms`) to list spaces and their IDs.
+- **supports-threads**: yes
+- **typical-use**: Interactive chat — team spaces or direct messages
+- **default-isolation**: Same agent group for spaces where you're the primary user. Separate agent group for spaces with different teams or sensitive information.
