test/changelog.test.sh drives changelog_fragments (order, marker, absent
dir), changelog_fragment_problem (every rule, file named each time), and
changelog_assemble (both shapes, canonical order, mixed-shape refusals).
test/changelog-assemble.test.sh drives the CLI against constructed trees:
exact-byte writes, provably read-only --check, every refusal from the
spec, the publisher/assembler round trip, and idempotence.
Closes#114.

lib/changelog.sh gains changelog_fragments (publication order: trailing
issue number descending, filename tie-break), changelog_fragment_problem
(the release-time rules moved onto the PR that writes the fragment, #112
D9), and changelog_assemble (canonical group order per D5, one shape per
repo per D4). bin/changelog-assemble folds changelog.d/ into one release
section, deletes exactly what it consumed, and --check proves the body
without touching the tree.
Part of #112. Closes#114 groundwork; tests follow.
