[PM-02] Extend script-docs.test.js for framework header validation

[DeveloperAlly]

Tracking issue for PM-02 in the Sprint 3 + Post-Migration Audit stream.

Scope:

• Implement Extend script-docs.test.js for framework header validation
• Keep changes isolated to the task branch/worktree
• Validate against docs-v2 governance rules before PR

[668308]

I am looking into this and plan to submit a PR shortly.

Plan:

1. Review the current docs test harness and framework header validation path.
2. Extend script-docs.test.js with targeted validation coverage.
3. Run the relevant test flow and submit a focused patch.

ETA: review now, implementation shortly after.

Validated on docs-v2 on March 11, 2026. Closing as implemented by tests/unit/script-docs.test.js, which includes FRAMEWORK_REQUIRED_TAGS and validates framework header coverage.
