fuzz: translate fuzz-hsm_encryption to fuzz-hsm_secret.

Copy corpora, since it's the same code paths.

Thanks Claude!

The short version

What changed, and why it matters

This commit adds a new fuzz test and its test data. Fuzz tests are automated tools that throw random or crafted inputs at a piece of code to look for crashes or bugs. The new test exercises the encryption and decryption routines for the node's HSM (Hardware Security Module) secret, but it does not change those routines themselves. There is no indication this commit fixes or introduces a security vulnerability.

Recommended action

No security action required; this is a test-only addition. Reviewers may optionally verify that the copied corpus and harness correctly exercise the intended code paths and that the harness does not introduce undefined behavior in its casts or memory handling.

Security signals we found

01

Adds fuzzing coverage for HSM secret encryption/decryption roundtrip

02

No changes to cryptographic implementation or production code paths

03

Assertions in fuzz harness are expected invariants, not runtime checks
