fix(free-models): stop reporting discontinued Pollinations models as free (#11441)

Browse Source 
Merged into release/v3.8.51 via batch validation (combined tree): vitest autoCombo suite 32/32 incl. free-regime-not-read-by-predicate, static gates green (file-size / complexity / cognitive / changelog-integrity / typecheck:core). Compiler-checked FREE_REGIME_TRAITS table eliminating the discontinued-as-free routing bug — excellent work, thanks @maxmad64bis!
