Add documentation for the CLI commands referenced in the Create Tool
modal on the platform (crewai tool create, crewai tool publish,
crewai tool install). These commands manage tools on the CrewAI
platform registry — distinct from PyPI publishing.
Changes:
- New guide: docs/en/guides/tools/platform-tools-cli.mdx
Full lifecycle: create → implement → publish → install
Covers visibility flags (--public/--private/--force)
Includes platform vs PyPI comparison
- Updated create-custom-tools.mdx tip to cross-reference both guides
- Added new page to docs.json navigation (all versions)
Resolves EPD-76
