fix(detect_changes): impacted_symbols always empty for projects inside git worktrees

[lg320531124]

Bug

detect_changes returns an empty impacted_symbols array for projects that reside inside git worktrees. The change detection itself may work (detecting which files changed), but the downstream symbol-impact analysis fails to resolve the symbols.

Possible cause

Git worktrees have a .git file instead of a .git/ directory. If the change detector resolves the git dir by reading the worktree pointer but the symbol resolver treats .git as a regular directory, the git metadata lookup fails silently and returns empty results.

Thanks for writing this up. This duplicates #659, which is the canonical detect_changes worktree impacted-symbols issue. The corresponding fix PR is #672, so I am closing this duplicate and keeping status on the canonical tracker.
