In `@otdfctl/cmd/tdf/decrypt.go`:
- Line 89: Add a reachable command-level regression test for decrypting with the
--out option, asserting that the resulting committed output file has permission
mode 0o600. Place it in the active test suite rather than the disabled BATS
suite and exercise the real decrypt command path.

Security Misconfiguration
Reachability: External
Exploitability: Moderate
CWE: CWE-732 — Incorrect Permission Assignment for Critical Resource
Add a decrypt command regression test.
The existing BATS suite is disabled, and the --out path has no command-level permission assertion. Add a reachable test that decrypts with --out and asserts the committed file mode is 0o600.
