Implements the M3-frontend slice of the §22 multi-project track, per
docs/superpowers/specs/2026-06-03-m3-frontend-design.md (design merged in
#10). Completes the runtime-config cut 0.33.0 (M3-backend Plan A) began.
Frontend:
- DeploymentProvider boots GET /api/deployment → {name, tagline,
defaultProjectId, projects}; brandTitle() neutral 'RFC' pre-fetch fallback.
- /p/:projectId/* routing with generic /e/<slug> segment. ProjectLayout
fetches /api/projects/:id, applies per-project theme (reset on switch),
provides ProjectContext, guards the corpus (served only for the default;
others get NotServedPlaceholder — decouples this slice from Plan B).
- Directory at / (2+ projects) with N=1 redirect into the single project;
ProjectSwitcher in deployment chrome; entry-noun by project type.
- VITE_APP_NAME hard cut: removed from vite.config + index.html; the 6 brand
reads now use deployment.name via context; static <title>RFC</title> + JS
document.title. Internal /rfc·/proposals links → /p/<project>/e|proposals
via lib/entryPaths.
Backend:
- GET /api/deployment returns default_project_id (the guard contract).
- Server-side 308s: /rfc/<slug>, /rfc/<slug>/pr/<n>, /proposals/<n> →
/p/<default>/… . nginx (testing + prod) routes /rfc/ and /proposals/ to
the backend.
Tests: 3 new backend redirect/deployment tests (438 pass); Vitest unit for
DeploymentProvider, ProjectLayout (theme/guard/404), Directory (11 pass);
clean build with no VITE_APP_NAME. Playwright e2e deferred until Tier-1 seeds
a registry (see CHANGELOG 0.35.0 step 5).

Adds two read endpoints that replace the build-time VITE_APP_NAME with a
runtime-config surface: /api/deployment returns deployment name/tagline plus
the projects visible to the caller (gated filtered by membership, unlisted
omitted from enumeration per §22.5); /api/projects/:id returns one project's
config and optional theme overlay, gated behind the §22.5 read gate.
