fix: rebrand the HTML report as Mobilewright end to end

[rahul-system]

Fixes #137.

The HTML report still identified itself as Playwright in several user-facing places. Each one had a different cause, so they are fixed together:

• The page renamed itself back to "Playwright Test Report" after loading. brandReport replaced the <title> tag and a document.title="…" fallback, but Playwright 1.63's bundle emits that fallback with backticks, so the SPA reset the tab title on every navigation. The replacement now matches ", ' and `.
• The end-of-run hint printed npx playwright show-report. That line is written straight to stdout from a private helper in Playwright's HTML reporter, so packages/mobilewright/src/html-reporter.ts subclasses the reporter and rewrites it to npx mobilewright show-report.
• A report configured in mobilewright.config.ts went to playwright-report/ unbranded. Only the mobilewright test --reporter html flag forced outputFolder. defineConfig now routes html reporter entries through the branded reporter too, which defaults the folder to mobilewright-report.
• merge-reports --reporter html produced an unbranded report. It ran Playwright's own reporter and renamed the output folder afterwards. It now uses the branded reporter directly, so the rename is gone.

Branding moved from the test command action into the reporter's onExit, so it follows the reporter instead of being attached to one CLI path.

Also: docs/src/test/sharding.md told CI to upload playwright-report/, which merge-reports never produces, and .gitignore did not cover mobilewright-report.

Verification

• npm run lint clean; 707 unit tests pass, 1 skipped.
• New packages/mobilewright/src/reporter.test.ts covers the title replacement in all three quote styles — the regression that this PR fixes.
• End-to-end on a real Android device (Galaxy A50, mobilecli): --reporter html writes to mobilewright-report/ with no playwright-report/ created, the hint prints npx mobilewright show-report mobilewright-report, and the report contains no "Playwright Test Report".
• Opened the served report in Chrome: tab title stays "Mobilewright Test Report" on the list and on test-detail pages, the header brand and favicon render, and the screenshot fullscreen overlay opens and closes on Escape.
• Sharded path: a --reporter blob run merged with merge-reports --reporter html lands directly in mobilewright-report/, branded.

Note for reviewers

html-reporter.ts subclasses Playwright's internal lib/runner html export and reads _outputFolder. That is not public API and will need a look on each Playwright bump.

Walkthrough

The CLI and configuration now resolve HTML reports to a bundled Mobilewright reporter. The reporter defaults to mobilewright-report, applies Mobilewright branding, and rewrites the displayed show-report command. Branding replacement supports single, double, and backtick quotes, including external report bundles. Tests, documentation, and ignore rules use the new report directory.

Priority: ➖ Normal

Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to 9fe4b

The branded reporter lifecycle and configuration wiring preserve the intended Mobilewright report behavior, with no established merge-blocking risk.
