install --skill (singular) silently succeeds without installing skill files

[jpchavat]

Description

Running playwright-cli install --skill (singular) succeeds silently but does not install skill files to .claude/skills/playwright-cli/. Only playwright-cli install --skills (plural) works correctly.

Steps to Reproduce

1. Run npx @playwright/cli install --skill in a project directory
2. Observe output:

   ✅ Workspace initialized at `/path/to/project`.
   ✅ Found chrome, will use it as the default browser.
   

3. Check .claude/skills/playwright-cli/ — no SKILL.md or reference files created
4. Now run npx @playwright/cli install --skills (plural)
5. Observe output now includes: ✅ Skills installed to .claude/skills/playwright-cli
6. Skill files are correctly created

Expected Behavior

Either:

• install --skill (singular) should be rejected with an error or suggestion ("did you mean --skills?")
• Or install --skill should behave the same as install --skills

Actual Behavior

install --skill silently initializes the workspace but skips the skill file installation step. No error or warning is shown. The install --help output only documents --skills (plural).
