Local: forget untouched browse records of folders not browsed for 30 days

Local browse records can be most of a large catalog (85k photos, 90 %
Local: 313.5 MB snapshot). Untouched Local records of folders whose last
browse is older than library.preferences forgetLocalDays (default 30,
0 = never) are now removed from the catalog when the library opens (and by
library.forgetLocal {dryRun?, days?}), as journaled, non-undoable ops, then
compacted in the background. Files and XMP sidecars are never touched;
browsing the folder again catalogues them afresh.

Untouched = a Local file record, not deleted, not a virtual copy, whose
state still hashes to the fingerprint taken when the browse catalogued it
(any change keeps it); records from before fingerprints need every
user-editable field empty/default. Kept too: records in albums (or as
cover), stacks, sources of virtual copies, visible/selected/edited ones,
ones referenced by undo/redo, ones with a smart preview.

Per-folder last-browsed times live in the catalog (Op::SetBrowsed,
normalised with folder_key; re-stamped at most hourly). Old catalogs load
unchanged; folders without a time are stamped now, so nothing is forgotten
on the first open after the upgrade.

persist_bench (85k photos, 76.5k Local, every 7th folder recent, 1 in 50
rated): 63.8k forgotten, plan 162 ms, snapshot 313.5 MB -> 94.9 MB.
Settings -> Performance -> Local folders.

//! Forgetting untouched Local browse records.
//!
//! Browsing a folder (Local) catalogues its photos as `local` records so they can be shown,
//! rated and edited in place. Most are only ever looked at, and on a large disk they can be most
//! of the catalog. A record is **forgotten** (removed from the catalog, never from the disk —
//! files and XMP sidecars are not touched) when all of these hold:
//!
//! - it is a Local record ([`Photo::local`]) of a file, not deleted, not a virtual copy;
//! - its folder was last browsed more than `days` ago ([`Catalog::last_browsed`]). A folder with
//! no recorded time (a catalog from before this existed) counts as browsed *now*: it is stamped
//! with the current time and nothing in it is forgotten this time;
//! - it is **untouched** ([`Photo::untouched_local`]): nothing about it changed since it was
//! browsed — see below;
//! - nothing refers to it: no album holds it or shows it as cover, no stack holds it, no virtual
//! copy was made of it; and the caller (the engine) says it isn't in use (visible, selected,
//! in the undo history, has a smart preview…).
//!
//! **Untouched.** A record catalogued by a browse carries a fingerprint of its whole state at
//! that moment ([`Photo::local_baseline`]). It is untouched while its state still hashes to that
//! fingerprint, i.e. *any* change since — develop settings or history, versions, rating, flag,
//! label, any metadata (title, caption, keywords, location, copyright…), capture time, crop,
//! rename or relink, culling scores, file content — keeps it. Records without a fingerprint
//! (browsed before fingerprints existed) are judged by their data alone and kept unless every
//! user-editable field is still empty / default: no rating, flag or label; develop settings equal
//! to the import defaults with no history, versions or edit time; no title, caption, alt text,
//! description, keywords, creator, copyright, rights, location or GPS; no culling scores.
//! When in doubt a record is kept.
//!

- Smaller, faster catalogs: photos you only looked at in Local (never added, rated or edited) are forgotten once
their folder has not been browsed for 30 days — your files and sidecars stay, and browsing the folder shows them
again. Change the period (or turn it off) in Settings → Performance.
