fix(ci): Improve flaky test issue deduplication

[mydea]

report-ci-failures.mjs opens one GitHub issue per failing test, keyed on a normalized job + test name. Several variant patterns weren't being stripped, so the same flaky test kept opening duplicate issues. This widens both normalizers.

normalizeJobName now also collapses:

• (Node 22) and (n/m) shard groups (in addition to the existing (22) / (TS 3.8))
• All Playwright bundle/esm build configs into a single Playwright Tests bucket (e.g. bundle_tracing, bundle_tracing_replay, esm (1/4)) — the same profiling flake was filing an issue per config
• E2E -node-20-18 app-name version suffixes

Non-version parentheticals such as (Orchestrion) are preserved.

normalizeTestName now also strips:

• The [chromium] › browser project prefix
• Playwright test.ts:33:11 line/column locations — these drift whenever the test file is edited, silently reopening the same flaky issue under a new title
• The trailing [esm] / [cjs] module-format suffix (the main gap — the old describe-block form was handled but the newer suffix form was not) and the bare esm/cjs > describe segment, so both forms converge

Verified against current open Flaky Test issues: the [esm]/[cjs] postgres/mysql pairs collapse to one, the profiling test across bundle_tracing / bundle_tracing_replay / esm (1/4) collapses to one, and line-drift variants merge.

Note: dedup still matches on exact issue title, so existing issues (which carry the old normalized titles) won't retroactively merge — the next run files them once under the new canonical titles. Bulk-closing the current flaky issues after merge is recommended.

Missing normalization regression tests

Low Severity

This fix expands normalizeJobName and normalizeTestName, but the PR adds no unit tests for those cases. Without table-driven examples (Playwright job folding, [esm]/[cjs] titles, line-number stripping), future regex edits can silently break flaky-issue deduplication again.
