pub fn HealExecutableBits(InstalledAt: &Path)Expand description
Walk an installed extension directory and chmod +x any file that
matches the same executable heuristic as fresh installs. Used on the
idempotent reinstall path so users who installed extensions before
the exec-bit promotion landed don’t need to manually chmod shipped
binaries (rust-analyzer/server/rust-analyzer,
openai.chatgpt/bin/<triple>/codex, Dart-Code/bin/dart, etc.).
Errors are swallowed - this is a best-effort heal, never the reason
an install fails. A file we can’t open or stat just keeps its
existing mode and the extension’s spawn will surface the same
EACCES it would have anyway.
