refactor(dev): remove the minimal-registry escape hatch

`dev:minimal` existed because the tool registry was 71-82% of every workspace
route's module graph and aliasing it away was the only way to make dev bearable.
The metadata work removed that reason, so the hatch now buys almost nothing:

  before this stack   31.7s -> 20.0s cold  (-37%)
  after this stack    22.9s -> 20.7s cold  (-10%)

A 10% cold-compile win, on the run that happens once — restarts are ~4.2s either
way — is not worth what it costs. `tools/registry.minimal.ts` and
`blocks/registry-maps.minimal.ts` are 283 lines of hand-curated duplicates of the
real registries that **nothing keeps in sync** (no lint, no CI check, no test);
they are correct today only because someone remembered. And the mode is actively
misleading: it silently drops ~250 services and ~280 blocks, so anything
reproduced under it may not reproduce for real.

Removes both files, the `SIM_DEV_MINIMAL_REGISTRY` branch from `next.config.ts`
(including the whole `webpack()` hook, which existed only for this), and the
`dev:minimal` / `dev:full:minimal-registry` scripts.

Verified after removal: `tsc` clean, boundary + metadata + skills + monorepo
gates pass, and `next dev` starts and serves the canvas at 22.6s cold / HTTP 200.
