Lift business flags/const params out of Call/PostMount, add typed
flag defaults and policy gates, and realign the RFC acceptance bar to
"no Execute/Call body exists only to assemble params".

The single Dispatch hook assumed every command is one MCP call, so the
Shortcut projection could only ever describe a command, never run it. Split
dispatch into Invoke (assembled toolArgs) and Orchestrate (multi-step), keep
RunE as the escape hatch, and reject specs that declare anything other than
exactly one at construction time. Ctx gives both hooks the same typed flag
accessors so orchestration no longer reaches for framework-specific plumbing.
Catalog output stays byte-identical.
