Playwright bare --update-snapshots can consume test path as invalid mode

Playwright's --update-snapshots option accepts an optional mode value. In wrapper-script usage, a command like ... --update-snapshots e2e/spec.ts can be parsed as mode=e2e/spec.ts and fail with an invalid-choice error (all|changed|missing|none). Using --update-snapshots=all avoids ambiguous parsing and is robust when argument order is composed dynamically. Verified 2026-05 with Playwright 1.59.

When forwarding Playwright CLI args through wrapper scripts, pass --update-snapshots=all (or another explicit mode) instead of bare --update-snapshots if a positional test path might follow; otherwise the next token can be parsed as the mode.
