Function normalize_worktree

src/sessions/git_correlation.rs:310–324

Lexically normalizes a worktree path for stable equality: trims whitespace, converts backslashes to forward slashes, and strips trailing slashes (keeping a lone `/`). Deliberately does **not** hit the filesystem — writers should pass already-resolved worktree roots (e.g. from [`crate::worktree::git_worktree_root`]); this keeps readers and writers agreeing even when the path no longer exists.
