Implements HL (48-bit) arithmetic-immediate semantics:

  • HL.ADDI / HL.SUBI (64-bit add/sub with uimm24)
  • HL.ADDIW / HL.SUBIW (32-bit add/sub with uimm24, sign-extend 32-bit result)

These mirror the base 32-bit instruction semantics with a wider immediate.

Coverage: implemented_forms 501 -> 505 (+4 forms).

NOTE: per team rule, do not merge coverage-only PRs until cumulative delta >= 5% (unless explicitly requested). Keep open for batching.
