refactor: remove links, tags, and status fields from TPMJS spec

These fields are redundant as they already exist in package.json:
- links: Use package.json repository/homepage fields
- tags: Use package.json keywords field
- status: Not needed in tool metadata

Changes:
- Remove TpmjsLinksSchema type definition
- Remove links, tags, and status from TpmjsRichSchema
- Update validation logic to not check these fields
- Update all documentation (spec page, publish page, HOW_TO_PUBLISH_A_TOOL.md)
- Update example tool package.json
- Simplify field reference tables
