perf(runtime): remove measured steady allocations

Browse source 
Eliminate boxed production surface-override enumeration, retain vital modifier projections until the enchantment registry mutates, and measure DAT font widths without allocating a captured delegate. Preserve exact hashes, spell stacking, and glyph advances with warmed zero-allocation tests.

Validated by the focused rendering, UI, and spell suites, a zero-error Release build, and 8,409 passing Release tests with five pre-existing skips.
