/**
 * workspace/registration/resolution.ts
 *
 * The PURE resolution function and path helpers for the registered-workspace
 * registry. No disk, no git spawning, given a path, optional worktree-link git
 * metadata, and the registry state, it decides whether the path is covered by
 * (and which) registered root, remembered-declined, or unknown.
 *
 * SETTLED SEMANTICS (implemented exactly):
 *   - Coverage flows DOWN a registered root's subtree, never up: a root covers a
 *     path when the path equals the root or sits beneath it.
 *   - Worktree inheritance follows the git worktree→main-repo LINK, not path
 *     ancestry: if the path is a linked worktree whose main repo
 *     (git.mainWorktreeRoot) is covered by a registered root, the path inherits
 *     that registration even when it lives outside the root's subtree (the
 *     orchestration sibling-worktree case).
 *   - Nearest registered root wins when registrations nest (longest matching
 *     root path).
 *   - Declines are subtree-scoped at the root that was asked; a declined root
 *     covers its subtree the same way a registered root does.
 *   - When a registered root and a declined root both cover a path, the NEARER
 *     one wins; a tie resolves to `covered` (affirmative coverage beats a
 *     remembered "no").
