## Minimal duck-typed stand-in for Godot's built-in `ScriptBacktrace`
## class (the type of `script_backtraces[i]` entries inside `_log_error`).
## Mirrors the getter surface `_log_error`'s `script_backtraces` argument
## exposes (`get_frame_count` + per-frame file/line/function), so test
## suites for `editor_logger` and `game_logger` can exercise the
## backtrace-remapping path without a live script execution — Godot
## doesn't expose a constructor for the real ScriptBacktrace.
##
## Defaults to a single frame for existing tests, but can carry multiple
## frames so detail payload tests can verify full stack preservation.
