refactor: consolidate coercion contracts (#122458)

* refactor: consolidate coercion contracts

Centralize exact string, record, numeric, date, Boolean, argument, and structured-error coercions while preserving call-site semantics.

Migrate canonical-name collisions and deprecated internal SDK bypasses, deleting 55 net production/tooling lines. Expand declaration ownership enforcement to 101 allowed helpers and add a narrow export-completeness audit.

* fix: preserve standalone script coercions

Keep copied Control UI tooling self-contained and retain the trusted release harness module-relative source seam when the harness runs against an old target cwd.
