fix(perf): enforce route budgets and ratchet coverage thresholds

Allow mode: enforce in the report config, fail the command on over-budget and
unavailable routes, and make the markdown wording follow the configured mode.
Recalibrate the budgets against the webpack build (baseline x1.15, rounded up to
the next 10 KiB) now that the old Turbopack numbers no longer apply, so the
Docker image build gate blocks genuine bundle regressions instead of only
warning. Raise the Vitest coverage thresholds to the measured floor
(37.17/30.1/31.79/38.17 -> 36/29/30/37).

 ## Initial limits
 
-The first limits are **baseline bytes × 1.15, rounded upward to the next 10 KiB (10,240 bytes)** independently for raw and gzip. They are provisional size alerts, not validated speed targets. Baseline: local production build `build-TfctsWXpff2fKS`, Next 16.3.4 **Turbopack**; its source commit was not inferred.
+The limits are **baseline bytes × 1.15, rounded upward to the next 10 KiB (10,240 bytes)** independently for raw and gzip. They are size guardrails, not validated speed targets.
 
-The production build now runs webpack, so the numbers it reports are not directly comparable to the baseline below. Re-measured on the current webpack build the routes land at `/me` 786138/247738, `/news` 781601/245672, `/events` 782011/245923, `/search` 783262/246578, `/admin/catalog` 1172089/370843, `/admin/studio/furni` 1374128/440546 (raw/gzip). All remain inside the limits below, but `/admin/studio/furni` sits at ~98% of its gzip limit, so the next dependency added to that route will trip it. Recalibrate the table and `scripts/performance-budgets.json` together if the intent is to reset the baseline on webpack.
+Baselines were last recalibrated against a local webpack production build (Next 16.4.1, `next build --webpack`) and cross-checked against the report the Docker image build emits: `/me` 621460/195411, `/news` 616712/193199, `/events` 617121/193450, `/search` 618536/194216, `/admin/catalog` 1049094/330369, `/admin/studio/furni` 1397566/447765 (raw/gzip). The earlier Turbopack numbers (previous revision) were **not** comparable and were dropped.
+
+The image build compiles the app, then runs `scripts/performance-report.mjs` in the same `RUN` layer (`Dockerfile:48-53`). In `mode: enforce` a failing route therefore fails the image build, which blocks both the PR `preflight` job and the `deploy` job. Recalibrate the table and `scripts/performance-budgets.json` **together** in the same commit whenever the envelope legitimately grows (new route dependency, Next upgrade).

-Configured limits are positive integer bytes; `null` explicitly means observe-only. `scripts/performance-budgets.json` remains `mode: informational`. Exceeding a limit produces `over-budget` and a warning, with exit code 0. Missing production `BUILD_ID`, unsupported manifests, missing routes or missing referenced assets produce `unavailable` with a reason and **no partial/zero total**, also exit code 0. Malformed budget configuration or an unwritable output directory fails the command. This keeps initial CI reporting non-blocking while preventing invalid configuration from quietly disabling limits.
+Configured limits are positive integer bytes; `null` explicitly means observe-only. `scripts/performance-budgets.json` runs `mode: enforce`: an `over-budget` route prints `Performance budgets enforced: <route> (over-budget)` and exits non-zero. Missing production `BUILD_ID`, unsupported manifests, missing routes or missing referenced assets produce `unavailable` with a reason and **no partial/zero total**; under `enforce` an `unavailable` route also fails the command, so a bundler change that breaks measurement cannot pass quietly. Malformed budget configuration or an unwritable output directory always fails the command. Set `mode` back to `informational` only while recalibrating, never as a permanent state.
