feat(reporter): add omitTags option to omit auto-appended tags

[dcrousso]

the terminal reporters automatically append a test's tags to its title, which clutters the output when a test declares many tags

add an off-by-default omitTags option that suppresses the appended tags in the list, line, dot, github, and junit reporters

note that tags written directly into a test title are left untouched

fixes #41945

[dgozman]

Please add PLAYWRIGHT_LIST_OMIT_TAGS env variable support as well. I'd also put this line next to the first two options.

Same goes for other reporters.

🟢 CI is clear — the one failure is a pre-existing flake

Hi, I'm the Playwright bot and I took a look at the failing CI.

The single hard failure — mcp/annotate.spec.ts:57 on mcp-ubuntu-latest-chrome — is a known flake, not something this PR caused. This PR only touches reporter code (base.ts, dot.ts, github.ts, junit.ts, line.ts, list.ts, the omitTags type), which the MCP annotation-capture flow doesn't exercise.

Details

This PR adds an off-by-default omitTags reporter option. The diff is confined to packages/playwright/src/reporters/*, the generated types, docs, and tests/playwright-test/reporter-base.spec.ts. Nothing in it reaches the MCP server or browser automation.

Pre-existing flake / infra

• [chrome] › mcp/annotate.spec.ts:57 › should capture multiple screenshots in one annotation — flake. In the aggregated CI results this test fails 18 of 468 runs (≈3.8%) on mcp-ubuntu-latest-chrome, and it flakes across many other MCP bots (windows-chrome, ubuntu-webkit, ubuntu-firefox, macos-chrome/chromium/webkit, windows-firefox/msedge) too. Those failures land on SHAs this PR can't be responsible for — pushes to main (e.g. runs 29957712526, 29960743784, 30020951381) and another PR (feat(chromium): roll to r1235 #41974, run 30061238899). The signature is a timeout / Target page, context or browser has been closed, i.e. a browser-teardown timing race, not a logic break.

  Recent run history for this test on mcp-ubuntu-latest-chrome (oldest → newest, last entry is this PR's run):

• The six entries reported as flaky in the tests 1 job (library/video.spec.ts screencast tests, library/popup.spec.ts:260, library/chromium/chromium.spec.ts:211, page-event-request.spec.ts:181, page-goto.spec.ts:81) all passed on retry and are unrelated to reporter code — nothing to triage.
