Capture-set computation (INERT; Task 3-core, v0.133.0)

Browse Source 
Pure appbackup.ComputeCaptureSet(binds, hasClassification, tier, hddPath) → CaptureSet
{HasClassification, Paths, Skipped}: legacy short-circuit → tier filter (§2) → structural
guards → equal-Abs collapse (mandatory>optional) → containment dedup → sort. Slash algebra,
no filepath/FS/log. Structural guards (traversal / bare HDD drive-root / reserved backups/)
are load-bearing (the compose parser does not reject ..). Pure CrossAppOverlaps advisory
(WARN wiring deferred to 3a/3b). INERT — no engine consumes it yet.

Tests: Groups A-F (appbackup) + F-S3 no-seam wiring (stacks); all 6 §10 red-proofs verified.
Docs: architecture §3 aligned (felhom.eu 8d85da7).

> IMPACT from the spike (SP-3.4, already in §2.5): restic 0.14.0 does NOT error on a missing source
