test: run the cloak-profile integration test in CI

[code-yeongyu]

Summary

Routing node R4: run test/cloak-profile.integration.test.mjs in CI. It was in neither test script, and two things stopped it running as written:

• It called findCloakBrowserPath() directly. That function only globs a macOS CloakBrowser install, so the CLOAKBROWSER_BIN that CI sets was ignored and the test would throw on Linux.
• It asserted navigator.webdriver === false. Only CloakBrowser's patched binary reports that. The stock chrome-headless-shell that CI installs reports true; locally that assertion fails with actual: { webdriver: true, value: 'persisted' }.

The test is now split in two:

• Profile persistence. Site state (localStorage) and the fingerprint seed are reused across relaunches. It goes through connectCloakProfile's default, which resolves CLOAKBROWSER_BIN first, so it runs on any Chromium, CI included. It skips only when no browser exists at all.
• CloakBrowser hides navigator.webdriver on a reused profile. It needs a real CloakBrowser and skips with a reason when none is installed. CI does not have one; adding a third-party CloakBrowser download to CI is a separate decision.

Both use the repo's existing { skip, timeout: 60000 } pattern for live tests. The file is added to test and test:node.

Baseline gate (unedited base de08f48b)

The original file under node --test with a real local CloakBrowser: 1 pass. Under bun test: 1 fail, from the default 5 s timeout on a two-launch test.

After this change:

Browser available	node --test	bun test
chrome-headless-shell via CLOAKBROWSER_BIN (what CI has)	ℹ tests 2 ℹ pass 1 ℹ fail 0 ℹ skipped 1	1 pass 1 skip 0 fail
real CloakBrowser	ℹ tests 2 ℹ pass 2 ℹ fail 0 ℹ skipped 0	2 pass 0 fail
none	ℹ tests 2 ℹ pass 0 ℹ fail 0 ℹ skipped 2	(same skips)

Mutation proof

• src/cloak-profile.js launches with a fresh --user-data-dir each time instead of the profile directory. The routed persistence test fails: ℹ pass 0 ℹ fail 1. Restored; git diff --quiet -- src exits 0.

Audit numstat (frozen measurement tool, merge-base..head)

Removed: test 31, support 0, prod 0. Added: test 39, support 0, prod 0. Test files delta: 0.

Verify

The CI log on this PR should list cloak-profile.integration.test.mjs in both the bun test and node --test steps, with 1 pass and 1 skip.

Summary by cubic

Runs the cloak-profile integration test in CI. Previously it wasn't in any test script, only found a macOS CloakBrowser install via findCloakBrowserPath(), and asserted navigator.webdriver === false which fails on the stock Chromium that CI installs.

• Splits it into two tests: profile persistence runs on any Chromium (via connectCloakProfile's CLOAKBROWSER_BIN default), and the navigator.webdriver check requires a real CloakBrowser and skips with a reason if none is installed.
• Adds the file to both the test and test:node scripts.
