Bump version to 0.13.0 for MCU lockup follow-up and dependency refresh.

Covers two PRs merged after 0.12.0:

- PR #145 (MCU lockup recovery): App.safe_reboot() → App.reboot()
  in firmware liveness watchdog, new FleetTimeoutTracker for
  fleet-wide Slack alerting, interrupt + bootloader/RTC WDTs as
  defense-in-depth.
- PR #146 (dependency refresh): poetry update rollup covering all
  six Dependabot PRs (#139–#144) plus mypy 2.0.0 → 2.1.0 and
  others; CI poetry pin bumped to 2.4.1.

Also folds in the unreleased 0.12.1 (ESPHome 2025.11.2 firmware
compilation fixes from 6ca8ff7).

Minor version bump (0.12.x → 0.13.0) reflects the new
FleetTimeoutTracker feature; the firmware fix and dep refresh
alone would have been a patch bump.
