Attempt to recover from a stale build state. This is called when compilation fails due to missing/renamed/deleted files. It cleans stale Ninja deps, clears metadata caches, and forces Meson reconfiguration so the next compilation attempt has a fresh build graph. Args:

source_dir: Path,
build_dir: Path,
debug: bool,
check: bool,
build_mode: str,
verbose: bool,
enable_examples: bool = True,
