fix(build): // -> # comment delimiter in 21 Cargo.toml headers (valid TOML)

The estate attribution linter injects `// Owner:` lines, but `//` is not a valid TOML comment delimiter (confirmed: TOMLDecodeError at col 1) and breaks cargo manifest parsing on a fresh checkout of main. Convert to `#` — delimiter only; Owner string and SPDX headers unchanged. Same class of fix as the Coq `(* *)` header correction in #295.
