* fix(3259): non-mutating --help guard for native query handlers; reject --help as milestone version
Adds a dispatcher-level guard in query-dispatch.ts that short-circuits
to a non-mutating help stub whenever --help/-h appears in args destined
for a native mutating handler (fail-closed by default). Adds defense-
in-depth in milestoneComplete to reject --help/-h as a version value
before any disk write. Regression tests cover: per-handler --help guard,
registry-driven invariant across all mutating commands, handler-level
GSDError for both flags, and preservation of the #3019 CJS fallback
contract.
