fix: make Windows updates and CE personas reliable (#2340)

## Summary

Windows installs with slow native dependencies now get five minutes to
finish, and a real timeout is reported as an actionable terminal retry
instead of a wall of preceding npm deprecation warnings. Registry
`ETIMEDOUT` errors keep their network diagnosis, including after the
legacy-bin `--force` retry.

Compound Engineering personas are now included in the published CLI
bundle, with complete source-to-staged coverage for all persona
definitions and a clear startup error if the bundled assets are missing
or empty.

The PostgreSQL statement visible in the report was validated by the
existing real-Postgres schema reapply test. Its actual `caused by`
detail was truncated, so this PR deliberately makes no speculative
database change.

## Validation

- Dashboard updater tests: 22 passed
- CLI updater tests: 16 passed
- CE persona installer tests: 7 passed
- Published bundle persona assertion: passed against every source
persona
- CLI and CE plugin typechecks: passed
- Changed production/config lint and strict changeset validation: passed
- Real PostgreSQL schema reapply integration test: passed

## Summary by CodeRabbit

* **Bug Fixes**
* Windows CLI and dashboard updates now allow up to five minutes for
installation and restore Compound Engineering agent personas during npm
installs.
* Update failures now surface clearer, terminal timeout guidance (while
preserving specific network connection diagnostics) and avoid misleading
“deprecated”/generic timeout text.
* Persona assets are reliably included in plugin builds and bunded
persona installation now errors clearly when definitions are missing or
empty.
* **Tests**
* Expanded update and bundling coverage for the new 5-minute timeout and
error-handling scenarios.
