perf(schema): reduce retained integer validator allocations (#4360)

Construct integer formats directly while preserving bounds, refinements, metadata and current shared schema owners. Keep Incur-dependent CLI numeric coercion declarations unchanged.

Verify canonical advertisements, 126 numeric boundary cases, 974 actual CLI parser cases, broad source tests and real public-artifact SDK workflows. Record 72 normal tasks and 12 separate owned-inspector heap diagnostics with whole-family resource bounds; distinguish SDK spans and asymmetric audit overhead. Generate numerical report sections from receipts and reject stale tables through documentation conformance checks.

Closes #6236. Current-head CI and Greptile pass; actionable review findings are addressed. Codex review was unavailable due repository usage limits.
