Deduplicate cloud and executor skill listings before budgeting (#49127)

## Why

Skills available from both cloud and executor providers consume duplicate catalog space, leaving less room for descriptions of unique skills.

## What changed

- Prefer model-visible cloud skills over executor listings with the same `plugin:skill` name before allocating the metadata budget.
- Preserve aliases from the full visible executor inventory so filtering duplicates does not renumber remaining packages. Continue choosing full locators when they fit the budget better.
- Keep executor packages available through `skills.list` and `skills.read`, and retain executor listings when cloud skills are disabled.

## Testing

Add regression tests and a model-request snapshot covering description retention, stable aliases across turns, executor availability changes, package reads, and full-locator selection after deduplication.
