Description of your pull request and other information

Part of #2529 (one protocol class per module, named after it).

• Breaking: DRARP moves from pcapkit.protocols.application.rarp to pcapkit.protocols.application.drarp, and the old path keeps no re-export (refactor(corekit)!: move the byte-order field helpers into corekit (#1711) #1715, refactor!: remove every surviving re-export of a moved name or module #1744). pcapkit.DRARP and pcapkit.protocols.DRARP are unchanged.
• rarp.py keeps RARP alone, and RARP's dynamic DRARP alias is unchanged.
• Docs: a new drarp.rst, versionremoved:: 1.6.0 on the old path, and references retargeted. The VLAN, C/S-Tag and L2TP docs drop the per-index rule.
• Tests: the refactor!: remove every surviving re-export of a moved name or module #1744 ledger records the removal version, and a new test_drarp_unit.py fails before the move.

Cross-review (Sonnet) at 623a19e41: every claim passed except the ftp_data contrast. The two-file delta at 014a33dfa that fixes it was checked locally, so the head is GOOD TO GO. It checked that pcapkit.DRARP and pcapkit.protocols.DRARP still resolve, that the old rarp.DRARP path is gone with no re-export, that RARP's dynamic alias is unchanged, and that the new test fails before the move.

[JarryShaw]

Re-ran Unit Tests (run 41289240031). Attempt 1 concluded success but never created the Required checks passed or Plain unittest ordering jobs, so the head had no required gate. Attempt 2 is running. The review verdict is unchanged.
