storybored379andClaude Opus 5.5 0ae7a1925a Expressions: keep the runtime usable after errors and property reads ...

boa leaves the value stack of inner call frames behind when an exception
leaves a script (or a function called from Rust) from a nested call. Every
property read throws the pending-host-request abort from inside a prelude
helper, and so does any helper error (`thisComp.layer("Ghost")`), so the
thread's runtime filled up after ~100 evaluations of a pick-whip
expression: from then on every expression on that thread failed with
"RuntimeLimitError: reached the maximum stack size" and silently fell back
to its keyframed value (e.g. a follower layer stops following after ~90
render_frame calls).

Wrap the script and `__finish` in try/catch and rethrow from their own
frame, which unwinds the stack; backtraces (error line numbers) survive.
