pmccrary-oai fdeaa6c1ec Allow history and notes without experimental context capability (#47625) ...

## Why

Enabling `features.token_budget.use_history_notes_extension`, explicitly or through model defaults, rejected session startup when the model lacked `supports_experimental_context`, even with experimental mode disabled.

## What changed

Remove that startup restriction so token-budget history and notes can be used independently of the model's experimental context capability.

## Testing

Extend core tests to cover explicit configuration and model defaults on startup and cold resume, checking `new_context`, token-budget contexts, and `history_ingest_requested` metadata. Add app-server coverage for native history and notes tools and context-window hints without experimental context capability.
