Description of your pull request and other information

Part of #1103. Slice schema-data: the wave's prose in pcapkit/protocols/schema/, pcapkit/protocols/data/, corekit/fields/misc.py and corekit/protochain.py (15 files).

One fix: MesgIDOption.seconds in schema/internet/mh.py said "seconds since January 1st, 1970". It is an RFC 1305 NTP count from 1900, which is why post_process (edited by the wave) subtracts 2_208_988_800. NTPTimestamp.seconds in the protocol module already says 1900.

Every other wave-added comment was checked against the code and left alone, including the SchemaField.unpack NOTE (checked against prepare), the Quick-Start width NOTE (8 octets in the schema, RFC 4782 §3.2) and the ContextRequestOption note (a probe confirmed the SchemaWarning and zero padding).

File	AST equal
pcapkit/protocols/schema/internet/mh.py	True

Tests: test_mh_unit.py 52 passed; test_mh_mesg_id_fraction_unit.py 4 passed; tests/project 389 passed, 1 skipped.

Cross-review verdict on 1e3f8b717: GOOD TO GO (ran on Sonnet; author Opus). Labelled review: good-to-go.

• The 1900 epoch is correct. post_process subtracts 2_208_988_800 (25,567 days), _make_opt_mesg_id (mh.py:8110) adds it back, and RFC 4285 §6.1 specifies an RFC 1305 NTP timestamp. I re-read the encoder line myself.
• The PMIPv6 timestamp is separate. The one at schema/internet/mh.py:1140 really is on the 1970 epoch, and this PR leaves it untouched.
• Prose only. The AST guard shows no code change.
• Tests: test_mh_unit.py 52 passed; tests/project 389 passed.
