Commit Message

Add ct-ctgrind: Valgrind taint harness for constant-time primitives (#119)

* Add ct-ctgrind: Valgrind taint harness for constant-time primitives

Companion to the existing asm-grep harness. Catches secret-derived
memory access patterns (data-dependent loads, cache-timing leaks)
that asm-grep can't see because they don't compile to branches.

Mirrors the ct-fixtures fixture set under crabgrind+Valgrind taint
with a host-only driver that attributes per-fixture violations via
the memcheck error counter delta. Adds:

- ct-verify/ct-ctgrind/ workspace member: host-only binary via a
  Linux-conditional crabgrind dep. Non-Linux hosts get no-op stubs
  so the workspace still builds; running natively prints a clear
  "must be run under valgrind" error and exits.
- panic-handler feature gate on ct-fixtures so the same crate can
  link as rlib into a host std binary. The cross-target asm-grep
  builds keep the default feature enabled.
- .github/workflows/ct-ctgrind.yml CI job (ubuntu, apt valgrind).
- ct-verify/ct-ctgrind/Dockerfile for local iteration on macOS or
  Windows hosts where valgrind isn't available natively.
