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**: `imessage`
+- **terminology**: iMessage has "conversations." Each conversation is with a contact identified by phone number or email address. Group chats are also supported.
+- **how-to-find-id**: The platform ID is the contact's phone number (e.g. `+15551234567`) or email address. For group chats, the ID is assigned by iMessage internally.
+- **supports-threads**: no
+- **typical-use**: Interactive 1:1 chat — personal messaging
+- **default-isolation**: Same agent group if you're the only person messaging the bot across iMessage and other channels. Separate agent group if different contacts should have information isolation.
