Oleksandr Bezdieniezhnykh 23746ec61d [AZ-485] Add Public API barrels + STC-ARCH-01 (F4 close)
Closes architecture baseline finding F4. Every component now exposes
its Public API through `src/<component>/index.ts`; cross-component
imports go through the barrel. `scripts/check-arch-imports.mjs` plus
`STC-ARCH-01` in the static profile enforce the rule; tests in
`tests/architecture_imports.test.ts` cover AC-4/AC-5 + 2 exemption
cases. One F3-pending exemption (`classColors`) is documented in 5
places (barrel, consumer, script, doc, test) to avoid a circular
import.

Phase B cycle 1 batch 1 of 2 (epic AZ-447). Batch 2 is AZ-486
(endpoint builders) — blocked on this commit landing.

//
// FT-P-24 (row 47) — i18n detector path used at first boot
// Profile: fast — `quarantined` per blackbox-tests.md
// until the navigator.language detector is added in
// Step 4. Today src/i18n/i18n.ts hardcodes `lng: 'en'`
// so the test would assert the detector branch ran when
// no detector exists.
// FT-P-25 (row 48) — i18n persistence across reload
// Profile: e2e — `quarantined` per spec until detector
// + persistence land. Fast counterpart asserts the
// i18n instance carries no persisted-language detector
// so persistence can't have shipped yet.
//
// Both tests write the QUARANTINE marker (Vitest's `.skip` reporter line +
// inline reason). When the detector + persistence feature lands, the marker
// flips: removing `.skip` reveals the assertion, which then drives the
// production feature green.
//
// Black-box discipline: import `i18n` (the `00_foundation` public API) only;
// no React-component internals.
