Support scoped computed EventEmitter names

[ctate]

Summary

• Compile computed EventEmitter names with a provable constant prefix or suffix through exact-arity checked-dynamic dispatch, including literal/computed cross-matches and nullable receivers.
• Preserve listener identity and cycle collection; refuse names that may reach error, meta, or stream-internal events and typed listener-array introspection where signatures can vary.
• Correct narrow npm-static declaration projections needed for Commander's computed option listener registration.

Validation

• Plain and sanitized differential tests for computed names and nullable receivers.
• Plain and sanitized Commander registration differential.
• Compiler build, lint, compatibility check, and docs build.
• Full sandbox gate running.

This does not claim full static compilation of Commander's CLI; other compiler fences remain.
