## Summary

Adds a new permission UI for terminal pipeline commands (e.g. `cargo
test | tail`) that lets users selectively always-allow individual
commands in the pipeline, rather than only offering a blanket
always-allow for the first command.

Release notes:
- The terminal permissions UI now allows you to select individual
subcommands independently.
