chore: Sync sample script fixes between Lua and Python variants

Align recording/replay-buffer filename-from-text sample scripts so the
Lua and Python variants share the same robustness fixes: version note
corrected to v1.0.9+, override_cleared flag to suppress redundant proc
calls, enhanced sanitize_filename (control chars, trailing dots/spaces,
Windows reserved names), BOM handling with 4KB read limit, old-filter
override clearing on selection change, filter ID validation with proc
return-value logging, and defensive timer_remove in script_load.
