Index compiler catalogs for constant-time lookup

[julia-script]

Summary

• derive private scalar and intrinsic lookup maps once from the canonical frozen catalogs
• preserve catalog arrays as the ordering and inventory authority
• cover every actor, operation id, scalar alias, missing name, and object identity with exhaustive tests
• regenerate the compiler toolchain identity

Performance

Measured with isolated, non-interactive Vitest runs on the same host and against the one-pass documentation baseline.

Workload	Before	After	Saved
Frontend with stdlib	5.05s	3.95s	21.8%
Realized evaluator and Wasm	12.03s	9.23s	23.3%
