docs: fix documentation drift (19 items)

Critical fixes:
- Fix projman version mismatch (3.1.0 -> 3.2.0 in plugin.json)
- Update CLAUDE.md version to 4.1.0

Stale documentation updates:
- Add viz-platform to README.md (plugins, MCP servers, verification table)
- Add viz-platform to COMMANDS-CHEATSHEET.md (8 commands, hooks, MCP table)
- Add viz-platform and data-platform to CANONICAL-PATHS.md
- Add viz-platform and data-platform to CONFIGURATION.md
- Fix CHANGELOG.md tool counts (Layout 5, Theme 6, Page 5)
- Add data-platform to CLAUDE.md repository structure

Missing documentation:
- Create mcp-servers/viz-platform/README.md (21 tools documented)
- Add viz-platform SessionStart hook to COMMANDS-CHEATSHEET.md
