Twelve detector families move into one owner test each: 73 incident files
become describe blocks in ceo-section-loading-fixture (stale-fill race),
model-overlays, coverage-audit-evidence, autoplan-phase-observer,
native-auto-decide, outside-voice-evidence, eng-first-review,
plan-count-completion, plan-count-file-permission, ceo-mode-option,
plan-scope-selection and plan-count-prerequisite. Each block keeps its original
code and fixture, so every case still runs; only tests asserting the incident
file's own touchfile registration are dropped (41). Touchfile lists that named
an incident now name its owner.
* perf: remove repeated test work and preserve AUQ execution budgets
* fix: validate native evaluation fixture evidence at its actual boundaries
* fix: clarify deployment approval and recovery state transitions
* chore: document coverage and release v1.90.2.0
* test: preserve Windows scheduling and native no-change consent
* test: recognize verified reads through fixture symlinks
* test: isolate alias-name installation from runtime assets
