* feat: implement session restore for crashed/exited agents
Add true in-place session restore: same session ID, same worktree, same
metadata — optionally resuming the Claude Code conversation via --resume.
Core changes:
- Add TERMINAL_STATUSES, TERMINAL_ACTIVITIES, NON_RESTORABLE_STATUSES sets
and isTerminalSession/isRestorable helpers to types.ts
- Add SessionNotRestorableError and WorkspaceMissingError error classes
- Add restore() to SessionManager with 9-step flow: find metadata →
validate restorability → check/recreate workspace → get restore or
launch command → create runtime → update metadata
- Add restoredAt field to Session and SessionMetadata
Plugin extensions:
- workspace-worktree: exists() + restore() (git worktree prune + re-add)
- workspace-clone: exists() + restore() (git clone + checkout)
- scm-github: branchExists() via git rev-parse
- agent-claude-code: getRestoreCommand() finds latest JSONL session file
and builds claude --resume command
CLI + Web:
- Add `ao session restore <id>` subcommand
- Web restore API route uses sessionManager.restore() instead of spawn()
- SessionCard uses centralized TERMINAL_STATUSES/TERMINAL_ACTIVITIES
- Web types re-export core constants with sync tests

* fix: add "merged" to TERMINAL_STATUSES
The old inline isTerminal check included "merged" but when refactored
to use the TERMINAL_STATUSES set, "merged" was omitted. This caused
merged sessions (whose activity is not "exited") to incorrectly show
the "terminal" link and "terminate session" button.

* fix: enrich runtime state before restore check, remove dead branchExists
- Add enrichSessionWithRuntimeState() call before isRestorable() in
restore() so crashed sessions (status "working", agent exited) are
correctly detected as terminal and eligible for restore.
- Remove dead branchExists from SCM interface and scm-github plugin
(defined but never called anywhere in the codebase).

* fix: allow restore of crashed working sessions
Remove "working" from NON_RESTORABLE_STATUSES. The isTerminalSession()
gate already prevents restoring truly active sessions (activity is not
"exited"). This fix allows crashed agents (status "working", activity
"exited") to be restored, aligning core behavior with the UI which
already shows the restore button for this case.

* fix: distinguish missing branch from missing restore support
Split the compound condition so workspace restore gives an accurate
error message when branch metadata is null ("branch metadata is
missing") vs when the workspace plugin lacks a restore method.
