When a session's working directory is moved or renamed (e.g. `git worktree move`), the session file stays under the old cwd-encoded bucket while the new directory is empty. Resuming was lossy: - `--continue` rejected the terminal breadcrumb purely on cwd mismatch and then found nothing in the new bucket, silently starting a fresh empty session. - cross-project `--resume <id>` only offered to *fork* (duplicate) the session into the new directory, forcing manual id selection and leaving a stale copy. Detect relocation via the strong, low-false-positive signal "recorded cwd no longer exists on disk" and re-root in place with the existing `moveTo()`: - `continueRecent` re-roots the terminal's last session into the current directory when its recorded cwd is gone and the new location has no sessions of its own (otherwise behavior is unchanged). `readTerminalBreadcrumb` is refactored into `readTerminalBreadcrumbEntry` returning the raw cwd + session file so callers can interpret a cwd mismatch. - cross-project `--resume <id>` offers "Move (re-root)" instead of fork when the source directory is gone; a still-existing different project still forks. Tests: continue-relocation (re-root on move, no-hijack on plain cd, prefer local recent) and cross-project move-vs-fork routing.
