Verification v1: adopted intent and evidence-backed checks

[rajanbor]

Outcome

Verify declared pattern adoption without confusing schema validity with implementation correctness.

Inputs

• adopted .map/patterns/**/pattern.json
• acceptance criteria
• bounded static evidence providers

Outputs

• Verification Result v1 with pass, fail, unknown, and not-applicable checks
• human summary and versioned JSON

Constraints

• failure to inspect is unknown, never pass
• checks name their method, evidence, limits, and timestamp
• no repository mutation
• test execution is opt-in and separately permissioned

Acceptance criteria

• Finalize and add verification-result.schema.json with fixtures
• Define adopted intent and criterion IDs
• Implement contract and file checks first
• Add at least one safe static implementation check
• Document false positives, false negatives, and remediation boundaries

Depends on #103.
