workflow: delete docs/journals/ and docs/journal-archive.md

Strict application of the "Future-Use, not Verlauf" criterion to the
two remaining journal artefacts:

- `docs/journals/` (110 files): the per-iter and audit journals from
  2026-05-11 onward. Pure history; no live reader after the previous
  sweep. Entire directory removed.
- `docs/journals/2026-05-19-design-decision-records.md`: the one file
  that had live readers (`docs_honesty_pin.rs:108`, `parse.rs:80`,
  `duplicate_ctor_pin.rs:8`, three roadmap.md mentions) and was framed
  as a "relitigation guard". On re-examination its three asserted
  pinned phrases ("Regions were considered and rejected", the
  "demands annotations *because*" rationale, the prose-render
  placeholder statement) are rationale-prose, not load-bearing
  invariants — the test pinned itself, not a system property. Any
  Decision that still holds lives in the code, `design/contracts/`,
  or `design/models/`. Removed with the rest.
- `docs/journal-archive.md` (pre-2026-05-11 history): content-frozen
  long-tail history with no live reader. Removed; if anyone ever
  needs the pre-cutoff rationale they can `git log --before=2026-05-11
  --grep=<keyword>`.

Live-file consequences:
- `docs_honesty_pin.rs` `design_md_present_tense_anchors_present`:
  the three `records.*` assertions and the `read("docs/journals/…")`
  are dropped; the contract/model anchor pins remain.
- `duplicate_ctor_pin.rs`: the "why-two-overlays rationale lives in
  docs/journals/…" comment is replaced with the rationale inline.
- `parse.rs`: the "form-refinement rationale lives in docs/journals/…"
  comment is dropped (the rule body already states the refinement).
- `roadmap.md`: the decision-records mention in the DESIGN.md →
  design/ entry's body is dropped; the journal-archive.md `context:`
  pointers across ~12 closed entries are either rephrased to point
  at the relevant iter/audit (no path), or simplified to a one-line
  comment when the iter name alone carries the story.
- `CLAUDE.md` Roles section: the `docs/journal-archive.md` slot is
  removed; vocabulary note rephrased.
- `design/INDEX.md`: the Docs bullet drops `journal-archive.md`.
- `skills/README.md` bootstrap-rationale pointer rephrased.

`docs/specs/` and `docs/plans/` (per-milestone specs and per-iteration
plans) are unaffected — they remain the structured-design artefacts
they were before this sweep.

Workspace builds, full test suite green.
