feat(agents-api): Add alpha to hybrid search params in system tools…

… execution (#682)

<!-- ELLIPSIS_HIDDEN -->



> [!IMPORTANT]
> Add `alpha` parameter to hybrid search in `execute_system()` with
default value 0.75 and adjust `confidence` default to 0.5.
> 
>   - **Behavior**:
> - Add `alpha` parameter to `HybridDocSearchRequest` in
`execute_system()` for hybrid search when both `text` and `vector` are
present.
>     - Default `alpha` value set to 0.75.
> - Change default `confidence` value from 0.7 to 0.5 in hybrid search
context.
