docs: update README and documentation to match current state (v2.5.1)

- Update n8n version from v1.97.1 to v1.99.1 in README - Fix 7 broken documentation links to point to existing files - Standardize Docker image size to ~280MB across all docs (was inconsistent: 150MB/200MB/283MB) - Add missing npm scripts for test commands (test:essentials, test:enhanced-validation, etc.) - Update CHANGELOG.md with missing versions 2.4.0 through 2.5.1 - Update README_CLAUDE_SETUP.md to list all 21+ MCP tools (was only showing 6) - Document 5 additional npm scripts in CLAUDE.md - Update AI-capable nodes count to 263 (was 35 in old docs) All documentation now accurately reflects the current codebase state. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
