molecule-ai[bot] 3b5affb0d1 fix(github): refresh installation token when TTL < 10 min (#547) (#567)
Root cause: the github-app-auth plugin injects GH_TOKEN + GITHUB_TOKEN
into each workspace container's env at provision time (EnvMutator). Those
are GitHub App installation tokens with a fixed ~60 min TTL. The plugin
has an in-process cache that proactively refreshes 5 min before expiry —
but the workspace env is set once at container start and never updated.
Any workspace alive >60 min ends up with an expired token.

Fix (Option B — on-demand endpoint):

pkg/provisionhook:
  - Add TokenProvider interface: Token(ctx) (token, expiresAt, error)
    Lives in pkg/ (public) so the github-app-auth plugin can implement it.
  - Add Registry.FirstTokenProvider() — discovers the first mutator that
    also satisfies TokenProvider via interface assertion. Safe under
    concurrent reads (existing RWMutex).

platform/internal/handlers/github_token.go:
  - New GitHubTokenHandler serving GET /admin/github-installation-token
  - Delegates to the registered TokenProvider (plugin cache — always fresh)
  - 404 if no GitHub App configured, 500 + [github] prefix log on error
  - Never logs the token itself

platform/internal/handlers/workspace.go:
  - Add TokenRegistry() getter so the router can wire the handler without
    coupling to WorkspaceHandler internals

platform/internal/router/router.go:
  - Register GET /admin/github-installation-token under AdminAuth

workspace-template/:
  - scripts/molecule-git-token-helper.sh — git credential helper; calls
    the platform endpoint on every push/fetch; falls through to next
    helper (operator PAT) if platform unreachable
  - entrypoint.sh — configure the credential helper at startup

Why Option B over Option A (background goroutine):
  - The plugin already has its own cache refresh; nothing to refresh here.
  - Pushing env updates into running containers requires docker exec, which
    the architecture explicitly rejects (issue #547 "Alternatives").
  - Pull-based is stateless, trivially testable, zero extra goroutines.

Closes #547
