fix: make PSD runtime reactive to DSL and prop changes

[ubugeeei]

Finding

PSD character runtime parsing and declared animation registration can miss children/prop updates, leaving stale DSL or animation state during edits/HMR.

Evidence

• src/lib/character/character-unit/psd-character.tsx parse/effect dependencies.
• DeclareAnimationRuntime uses stable empty dependencies around mutable inputs.

Acceptance criteria

• Include relevant DSL inputs in effect dependencies.
• Avoid stale animation registration on HMR/prop updates.
• Add a minimal regression fixture if practical.
