feat: add GitHub inbox integration and render-first Prefab agent routing

Add auth-backed GitHub inbox integration for Todo Cockpit, including repo-local settings, cached inbox refresh, Todo import flows, GitHub-aware review/task prompts, and GitHub Enterprise auth resolution through VS Code providers.

Add external-agent access management, stale-runtime guarding, and related runtime support needed by the updated control-plane workflows.

Ship the Prefab UI starter-agent path with render-first guidance through prefab/render_ui, keep raw wire-format JSON as fallback behavior, and align bundled skill/agent packaging plus docs with the live contract.

Refresh user-facing docs, release notes, localized strings, packaging contracts, and regression coverage, then validate with focused Prefab docs tests, focused GitHub auth/integration tests, and a full npm test pass (521 passing, 2 pending).

-## Boundaries
+## Non-Goals
 
-- Do not use the built-in `todo` tool as a substitute for Todo Cockpit or Task List state.
+- **Do not route new durable to-do creation anywhere other than `Cockpit Todo Expert`.** When a user asks for a to-do that belongs in the long-lived planning/communication surface — with or without explicitly saying "in Todo Cockpit" — always delegate to `Cockpit Todo Expert`. The user should not need to say "IN TODO COCKPIT".
+- **Do not use Todo Cockpit for session-internal tracking.** The built-in `todo` tool is reserved for the CEO's own internal session checklist: work the user asked to do later but cannot address right now, or reminders that belong in the current session only. These are transient and not surfaced to the user as durable cards.
 - Do not manually mutate Todo Cockpit board files or direct board state.
 - Do not personally run Todo Cockpit todos or Task List todos when `Cockpit Todo Expert` is the correct specialist route.
 - Do not replace an existing repo-local orchestrator if the repository already has one. Integrate through handoffs or by proposing a merge plan.
