parseSearchQuery type: filter incomplete

[krwg]

Summary

Only type:release is enforced; type:note and others documented but ignored.

Target milestone: 2.8.5
Work branch: 2.8.5/issue-5-type-filter

---

Problem

README shows type:note page:docs. matchesSearchFilters only handles type:release.

Expected behavior

Implement category filters or document unsupported grammar explicitly.

Suggested approach

Map filters.type to item categories; add filter matrix tests.

Files / areas

• lib/engine.js
• lib/tokenize.js
• README.md

Acceptance criteria

• type:note behavior defined and tested
• Tests for page, app, path, tag filters
