feat(#335 ): prove drift/SQLite-WASM works in a real browser

Step 1 gate, web half. Building is not evidence, so this was run in a browser.

Assets: sqlite3.wasm (748 KB) and drift_worker.js (355 KB), both taken from
the SAME drift-2.34.2 release so they are built against each other. Validated
before use - the wasm has correct WebAssembly magic (0061 736d) and carries
SQLite 3.53.3; the worker is genuine compiled Dart JS.

Note the filename: the release ships `drift_worker.js`, not the
`drift_worker.dart.js` the docs name. The database URI was corrected to match,
which would otherwise have been a silent 404 at runtime.

Browser result, served over HTTP with COOP/COEP and Content-Type:
application/wasm:

  Using WasmStorageImplementation.opfsLocks
  PROBE-OK open+write+read
  PROBE-OK 6MiB round-trip (localStorage cap is 5MiB)

drift selected OPFS, the top storage tier, and round-tripped 6 MiB - data the
current localStorage-backed web build physically cannot hold. No exceptions.

Adds web/_headers for Cloudflare Pages: forces application/wasm on the wasm
asset and sets COOP/COEP for cross-origin isolation. Verified to ship into
build/web. Without COOP/COEP drift still works, falling back to IndexedDB,
which is slower but still unbounded next to localStorage - a performance tier,
not a correctness requirement.

web_probe/ is a standalone entrypoint that exercises ONLY the drift stack, so
a pass or fail is unambiguous without BLE and the rest of the app in the way.
It is not part of the app build.

Still no user data touched and no store switched over. The migration is the
next step.

flutter analyze clean, dart format clean, 497 tests pass.
