fix: opencode v2 lifecycle reporting (#3757)

* fix: support opencode v2 lifecycle reporting

* fix: repair Japanese docs

* fix: ignore payload-less OpenCode events

* fix: harden opencode v2 integration install and reporting

Follow-ups on top of the V2 lifecycle support:

- create `cli.json` when OpenCode has no V1 TUI preferences (`tui.json` or
  `kv.json`) to migrate, instead of only registering into an existing file
- settle stalled socket attempts with a plain connect timer, and resend the
  latest lifecycle state after a failed delivery so the pane cannot get stuck
- resolve the OpenCode state directory from `XDG_STATE_HOME`
- remove the managed `herdr-opencode` directory on uninstall
- document failed executions reporting `blocked`, keep the integration test
  environment independent of an inherited `XDG_STATE_HOME`, and simplify
  `reconcileBlockers` to reassign its map
