[Rule] Detect missing action verbs in bullet points

[SaharPak]

Add a rule that flags bullet points starting with weak or passive language.

Check each bullet point (lines starting with - or *) for:

• Starting with 'Responsible for' (already caught, but extend)
• Starting with 'Helped', 'Assisted', 'Participated in' (weak agency)
• Starting with a noun instead of a verb ('The project...', 'A system...')
• Not starting with an action verb at all

Reference the archetype's actionVerbs list to suggest replacements.

Severity: major if more than 50% of bullets lack action verbs, minor otherwise.
