1//! Shared process-name matching. Used by the run loop's app-pause guard and
2//! by the local-context detector probes, so both agree on what "process X is
3//! running" means — in particular both reject substring collisions
4//! (`zoom` must not match `zoominfo`) while allowing digit-versioned
5//! binaries (`obs` matches `obs64`).
6
7/// Case-insensitive token match assuming **both** arguments are already
8/// lowercased. A single-token target (all alphanumeric, e.g. `zoom`) matches
9/// a whole token of the process name, or a token that differs only by a
10/// trailing digit run (`obs64`); a multi-token target (e.g. `osascript -e`)
11/// falls back to substring so power-users can match a distinctive snippet.
12///
13/// The run loop pre-lowercases its target list once at settings load
14/// (`derived.app_pause_targets_lower`) and only lowercases the live process
15/// name per scan, so the hot path never re-lowercases every configured
16/// target for every running process.
