fixup! diigo-cache: date windows and search, designed as skipped specs (goal 1d)

Docs per the docs-files-api skill: a 1–2 line @file; what a declaration is or does in JSDoc on it, not in // comments or the file header.

 /**
- * @file the public page's filters — goal 1d, **not yet implemented**: the
- * design is pinned by the skipped suites in tests/query.test.ts and
- * tests/caches.test.ts ("public page filters").
- *
- * One filter, two spellings: devs pass a {@link FilterSpec} object
- * (`{ days: 7, q: "#weekly" }`); URLs carry the same fields as params
- * (`?days=7&q=%23weekly`, empty fields = absent). `q` also takes the
- * search operators large audiences already know — gmail's `after:`,
- * `before:`, `newer_than:7d`; Slack's `during:` (alias `in:`); GitHub's
- * `created:`/`updated:` — plus words, `"phrases"`, `#tag`/`tag:tag`, and
- * `-` negation.
- *
- * Time is UTC (Z) throughout; weeks are ISO 8601 (Monday first, so a
- * weekend stays together). Every window is half-open: `after` inclusive
- * from 00:00Z, `before` exclusive at 00:00Z — so GitHub's inclusive
- * `a..b` ranges are deliberately not offered.
- *
- * Applied while walking diigo's pages (updated-desc). `by=updated` finds
- * an old window by binary search over the sorted pages; `by=created`
- * walks from page 1 (an old bookmark edited lately sits near page 1).
- * Either way a request spends at most {@link FETCH_BUDGET} diigo fetches
- * (cached pages are free) and says so when results are incomplete.
