v1.90.2.0 perf: halve local free-suite time and preserve coverage (#2972)

Browse Source 
* 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
