- **added** — Expose `expiresAt` field in `Sandbox.list` and `Sandbox.get` to report the live timeout deadline of running sandboxes
- **added** — Display `TIMEOUT` column in `sandbox list` command showing the current session's deadline including any timeout extensions
- **changed** — `Sandbox.update({ timeout })` and `sandbox config timeout` now extend the currently running session so timeout changes take effect immediately instead of only applying to future sessions

###### Minor Changes

- Report the live timeout deadline of running sandboxes. `Sandbox.list` and `Sandbox.get` now expose `expiresAt`, reflecting the current session's deadline including any timeout extensions, and `sandbox list` renders it in the `TIMEOUT` column. `Sandbox.update({ timeout })` (and `sandbox config timeout`) now also extends the currently running session so an increased timeout takes effect immediately instead of only applying to future sessions.
