Standalone SHA-1 hashing implementation

Summary

Adds a standalone SHA-1 hashing implementation to the kernel.

Changes

New: SHA-1 hashing unit (src/include/sha1.pas, +210 lines)

  • Streaming API: SHA1Init / SHA1Update / SHA1Final
  • FIPS-180 compliant: 80-round compression (SHA1Transform), big-endian Invert helper, standard padding with appended bit-length
  • Types: TSHA1Context (state + 64-byte block buffer + length counter), TSHA1Digest (20-byte output)

Commits (4)

  • b9643a7b feature: SHA-1 Hashing
  • 3d334b8e feature: SHA-1 Hashing
  • 452cc0c8 Rebased on develop & remove test code from Kernel main.
  • c70c0b52 Rebase: Fixed accidentally removed unit tests.
