v0.21.11

PATCH release. Re-cut of v0.21.10's accounts-list redesign after the
v0.21.10 tag's release workflow failed on test_audit_all_clean (PR
#349 itself introduced 3 STX-TQ007 violations in the new
test__account_list_render.py plus a stale SK-301 SKILL.md WARN that
was still on develop). v0.21.10 exists as a "ghost" tag — no PyPI
artifact, no GitHub Release; operators install
scitex-agent-container==0.21.11 for the accounts-list redesign
PLUS the cleanup that unblocks the release pipeline.

Fixed

• chore(repo): clean 17 pre-existing audit-all violators (#348,
  unblocks #341/#344/release). Splits 7 STX-TQ007 violators in
  tests/scitex_agent_container/config/test__loaders_model_chain.py
  (12→29 tests, 1-assert each via shared Arrange+Act helper); 4
  STX-TQ002 (AAA-marker) violators in
  tests/scitex_agent_container/_runners/test__session_inbox.py;
  relocates tests/scitex_agent_container/containers/ test_apptainer_scitex_def_libxcb.py to tests/integration/ to
  satisfy PS-204 (orphan-test mirror rule) while preserving the
  libxcb / libgl1 / libglib2.0-0 regression guards; adds the
  required ## <N> Interfaces H2 and Four Freedoms blockquote to
  README.md (PS-107 / PS-110); trims SKILL.md from 6181→6070
  bytes to clear SK-301 (74-byte margin under the 6144 budget);
  fixes the post-relocation parents[2] repo-root walker in the
  moved apptainer-def test; and splits 3 STX-TQ007 violators
  introduced by #349 in test__account_list_render.py. No
  behaviour change — only test shape and docs.

Included from v0.21.10 (ghost tag — not on PyPI)

• feat(accounts): sac accounts list window-reset display
  (operator gripe via lead, 2026-06-09). See the v0.21.10 entry
  below for the full description. Headers, per-row reset hints,
  and rolling-window legend all ship in v0.21.11.
