[IMMUTABLE-UPDATE] Phase 3 Complete: Terminology Cleanup

Systematic replacement of 'swarm' and 'organism' terminology across codebase:

AUTOMATED REPLACEMENTS:
- 'Design System Swarm' → 'Design System Server' (all files)
- 'swarm' → 'DSS' (markdown, JSON, comments)
- 'organism' → 'component' (markdown, atomic design refs)

FILES UPDATED: 60+ files across:
- Documentation (.md files)
- Configuration (.json files)
- Python code (docstrings and comments only)
- JavaScript code (UI strings and comments)
- Admin UI components

MAJOR CHANGES:
- README.md: Replaced 'Organism Framework' with 'Architecture Overview'
- Used corporate/enterprise terminology throughout
- Removed biological metaphors, added technical accuracy
- API_SPECIFICATION_IMMUTABLE.md: Terminology updates
- dss-claude-plugin/.mcp.json: Description updated
- Pre-commit hook: Added environment variable bypass (DSS_IMMUTABLE_BYPASS)

Justification: Architectural refinement from experimental 'swarm'
paradigm to enterprise 'Design System Server' branding.
