feat(#72-77): test infra — CI matrix, bundle budget, ATTW, JSR, e2e scaffold

- CI runs on Node 20/22/24 matrix (#72)
- scripts/bundle-budget.mjs: per-file raw byte budget; ✗ entries fail CI (#75)
  Current: chatwoot ≤9KB (it ships the most surface), other providers ≤6KB,
  csp catalog ≤6KB, adapters ≤2KB, core ≤4KB, server stub ≤1KB.
- pnpm attw: invokes @arethetypeswrong/cli with --profile esm-only;
  release.yml runs it pre-publish so types-wrong publishes fail (#74)
- jsr.json: full sub-path map for JSR registry; release.yml publishes both
  npm and JSR (continue-on-error so a JSR outage doesn't block npm) (#76)
- vitest config excludes e2e/ — Playwright runs on demand outside the unit
  suite. e2e/intercom.spec.ts is the template; e2e/README explains setup (#73)
- release.yml: runs bundle-budget + attw before publish (#77 already had
  bumpp + changelogithub + provenance — completed by adding the two gates)

Closes #72 #73 #74 #75 #76 #77

+# Playwright e2e
+
+Real-browser smoke tests for each provider. Booted from a static fixture
+page that imports `ahize/<provider>` from the local build.
+
+## Setup
+
+```sh
+pnpm dlx playwright install --with-deps chromium
+pnpm e2e
+```
+
+## Adding a provider test
+
+1. Add a fixture entry to `e2e/fixtures/providers.json` with the test
+   credentials (use a sandbox/dev workspace).
+2. Drop a `e2e/<provider>.spec.ts` that asserts the script tag is injected,
+   `isReady()` flips to true, and `identify()` mutates the visible header.
+3. Most providers expose `data-*` attributes on their iframe — assert
+   visibility on those rather than provider-private DOM.
+
+## CI
+
+Disabled by default (requires real credentials). Wire `secrets.E2E_*`
+on the repo and uncomment the `playwright` job in `.github/workflows/ci.yml`
+to enable.
