Schema definitions rewritten with shorter helpers

Almost every input schema was shortened, which accounts for most of this release's diff size.

What

Almost every input schema in the bundle was rewritten to use short internal helpers instead of long-form calls, including Grep's parameters, the workflow tool, feedback drafts, notebook edits and session records. Field names, descriptions and validation are unchanged. This accounts for most of the diff size in this release.

Evidence

Enable multiline mode where . matches newlines and patterns can span lines (rg -U --multiline-dotall). Default: false.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
