Phase 5: Add immutable file headers to all protected files

Added protection headers to 9 critical files:

JSON Files (x-immutable-notice field):
- .dss/schema/api.schema.json
- .dss/schema/tokens.schema.json
- .dss/schema/components.schema.json
- .dss/schema/workflows.schema.json
- .dss/schema/guardrails.schema.json
- dss-claude-plugin/.mcp.json

YAML File (comment header):
- .dss-boundaries.yaml

Markdown File (HTML comment):
- API_SPECIFICATION_IMMUTABLE.md

Python File (docstring header):
- dss-mvp1/dss/validators/schema.py

Each header includes:
- Protection notice
- Reason for immutability
- Last modified date
- Bypass instructions (DSS_IMMUTABLE_BYPASS=1)
