v2.55.2

Deep-QC P1 1b — required-param validation. Mutating/destructive actions that
hard-indexed required params (p["name"], p["index"], p["color"], …) now
return a structured error instead of crashing with an unhandled KeyError.

Fixed

• Guarded: timeline set_current/set_name/set_start_timecode/add_track;
  timeline_item set_property/set_clip_enabled; project_manager
  create/load/import_project/export_project/archive/restore; marker
  delete_by_color (clip/timeline/item, destructive); layout_presets
  save/export; project_settings set_name/set_setting.

Validation

• Full offline suite green (1286 tests; tests/test_p1_param_validation.py). Pure
  input-validation; no Resolve behavior change for valid inputs, no live run needed.
