Eric Traut 08b07eef12 Preserve daemon diagnostics and include updater logs in reports (#49843) ...

## Why

Detached launches truncate stderr logs, losing details from previous failures. Updater handoffs can also leave existing writers with stale offsets after truncation.

## What changed

- Record daemon lifecycle and update stages with timings, outcomes, and typed OS errors, omitting error messages and context.
- Preserve the last 256 KiB of nonempty stderr logs before truncation and use append handles to prevent gaps during handoff. Preservation failures do not block launch.
- Attach current and previous updater log tails when log inclusion is enabled for a report, with a 512 KiB total limit and legacy filename fallback. Skip missing, empty, and nonregular files.

## Testing

Add regression coverage for diagnostic error redaction, bounded log preservation, append behavior during handoff, attachment selection, and updater logs in captured report uploads.
