- Added session-domain modules and exports for session-entries, context, listing, loader, and migrations.
- Changed persistence to async append writes plus writeTextAtomic, removing sync line APIs.
- Added compaction-aware session context rebuild with dangling tool-call cleanup.
- Added resumable session resolution with status inference, id/stem/suffix matching, and backup recovery.
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.
