pub const GIT_DIR_NAME: &str = ".git";Expand description
The directory-entry name that marks a git repository root — either an
ordinary clone’s .git/ directory, or a linked worktree’s .git
file (a gitdir: pointer, e.g. how this repository’s own
.claude/worktrees/* are laid out). A single source of truth for that
name (issue #1435): before this constant existed, IGNORED_DIR_NAMES
below and brink-project-config’s find_config walk-up bound each
hardcoded their own ".git" literal, free to drift apart.
