## Summary
- Replace per-test `npm run e2e` commands in the Playwright PR comment
with a single combined command listing all unique failing spec files
- Remove unused `isSnapshotFailure` and `generateTestCommand` helper
functions
- Makes it easier to copy-paste and re-run all failures at once

## Test plan
- Verify the generated PR comment format by inspecting the next CI run
with test failures
- The command section should show a single `npm run e2e` with
backslash-joined spec file paths

## Summary by cubic
Simplified the Playwright PR comment to a single copy-paste command that
re-runs all failing spec files at once. This reduces noise and speeds up
local reproduction.

- **Refactors**
- Generate one command using backslash-joined unique failing spec paths;
sanitize file paths.
- Remove isSnapshotFailure and generateTestCommand; drop snapshot flags
and error previews from the comment.

> [!NOTE]
> **Low Risk**
> Only changes CI comment output formatting/commands and removes unused
helpers; no impact to test execution itself, but could slightly affect
how developers re-run failures locally.
> 
> **Overview**
> Simplifies the Playwright PR comment’s macOS re-run section to output
a **single** `npm run e2e` command listing all *unique failing spec
files*, instead of generating per-test `-g` commands.
> 
> Removes the snapshot-detection and per-test command helpers
(`isSnapshotFailure`, `generateTestCommand`), dropping
`--update-snapshots` suggestions and reducing comment noise.
