fix(pcap): read Header._read_protos in the file's byte order (#2312) - #2334

Conversation
Problem: Header._read_protos unpacked with lilendian=True whatever the file's byte order, so on a big-endian file 00 00 00 01 read as LinkType.Unassigned (16777216) rather than ETHERNET. Fix: read in self._byte, falling back to little-endian before read() has set it. The docstring says what it reads; the 1.5.0 changelog entry for #1125 is extended and CHANGELOG.md regenerated. Test: test_header_magic_protos_unit gains a big/little x size 1/2/4 case and a parsed big-endian header case; both fail on origin/main.

Problem: of the 60 pull requests merged in the #2312-#2407 range, only #2334, #2336, #2337, #2340 and #2348 wrote a 1.5.0 changelog entry, and #2398 and #2403 only reworded lines that were already there. Every other user-visible change in the range -- wire-semantics fixes, maker guards, reassembly behaviour, public-API and error-message changes -- went unrecorded, so the entry no longer describes the release. Fix: one entry per user-visible pull request, in each module section's existing style and ordered by the issue it closes. Two pairs share a bullet, since each is the direct follow-up of the other: #2393 with #2401, and #2405 with #2407. The diff on the entry file is purely additive. Internal-only work is left out deliberately: dependency and action bumps (#2387 to #2391), test-only and docs-prose passes (#2333, #2376, #2379, #2380, #2402), the unreachable-branch removal (#2378), and the #: comment marker the HIP Group and Packet crawlers now write (#2381). That last one renders nothing either way: the marker lands inside the generated _missing_ body, conf.py's exclude-members drops _missing_ from autodoc, and a comment in a method body is not an attribute comment to begin with. #2392 and #2403 are recorded together, under Added rather than Fixed, for the declarations they introduce: __proto_key__ on the seven classes owning a __proto__ registry (#2392), __proto_dest__ on the four enum registries and Vendor.PROTO_DEST to generate it (#2403). Both PRs added the autodoc entries, so both are rendered public attributes. #2392's rejection-message change is deliberately not recorded as a fix: the bare "code must be ..." text it prefixed came from _check_code, which #2193 introduced and which is in no release tag -- absent at v1.5.0b14 -- so no released version ever emitted it. #2403 is no longer skipped as internal because it reworded an existing bullet to name __proto_dest__ while nothing credited the attribute's introduction. Four claims are corrected against the source rather than carried over: FTP_DATA shipped in pcapkit/protocols/application/ftp.py from 1.0.0, not 1.4.0 (class FTP_DATA(Raw) is there at v1.0.0); #2365's pre-fix fallback read cmmd.value, so a .value-carrying object was accepted unchecked rather than raising; #2399 left the dpkt adapter and the adapters' ModuleNotFound raises alone, so it claims no universal prefix; and #2397's old tail did name the version it got, so the entry quotes it and gains the :issue:`2302` it was missing. #2370's "a Section Header Block ... still fails" sentence is dropped: #2369 settles the byte order first, and an SHB built from raw octets with ctx=None now rebuilds byte-exact in both byte orders. CHANGELOG.md is regenerated with util/changelog_md.py. Test: tests/project/ in full, 0 failures, including test_changelog_md.py's in-step and supported-subset checks; util/changelog_md.py --check reports the two files in step; the entry parses under docutils with no structural warning.
