Preserve explicit user goal updates in Guardian authorization (#47811)

## Why

Explicit user goal edits can restrict permitted actions, such as “Inspect only; do not publish.” Guardian needs these edits as authorization evidence even though they are recorded as contextual messages.

## What changed

- Add `UserGoalUpdate` and a recording API for objective, status, and clear updates without scheduling a model response.
- Use host annotations to retain goal updates in Guardian review history and root authorization evidence, and invalidate cached authorization when updates are recorded.
- Omit oversized objectives whole and mark their evidence incomplete so truncation cannot turn a restriction into a grant.
- Keep item injection from updating shared model and multi-agent metadata.

## Testing

Extend authorization, retained-context, and review snapshot tests to cover goal-edit cache invalidation, root goal visibility from child threads, and restrictive goals reaching Guardian alongside managed policies.
