Parser Frontend Performance & API

Maximize Ori's parser frontend throughput and API quality across the full pipeline — lexer, parser, and Salsa integration — by amplifying existing architectural strengths (parallel tag arrays, static binding power tables, Elm-style progress tracking) and closing identified gaps (file hygiene blockers, missing #[inline] annotations, inactive incremental parsing, Salsa query granularity). Target: measurable throughput improvement on existing benchmarks with zero regressions.
