Parfii-bot 32f2e8a288 feat(wave15): kei-dna-index + kei-fork Option-D path convention fix
46 crates, 744 tests green (up from 726 at v0.31.0).

## kei-dna-index (new) — read-only adjacency analysis over kei-ledger

Answers "who else touched same files / solved same task / ran nearby in
time". Does NOT mutate ledger — parses DNA strings in memory. Respects
SSoT (DNA string is the single source; columns NOT duplicated).

Public API:
- adjacent(target_dna, kind) — 5 kinds: Scope / Body / Role / Temporal / All
- cluster_by(scope|body|role) — group DNAs, ≥2 members per cluster
- precedent(body_sha, status_filter) — find past successful runs of same task
- stats — totals, unique scopes/bodies, avg cluster size

CLI:
- kei-dna-index adjacent --dna D [--by kind] [--limit N] [--db PATH]
- kei-dna-index cluster --by scope|body|role
- kei-dna-index precedent --body HEX [--status merged|failed|all]
- kei-dna-index stats

18 tests pass (13 integration + 5 parsed unit). Zero sibling deps
(no kei-ledger, no kei-agent-runtime path imports — standalone tool).

Separation of concerns: kei-ledger stays PURE provenance primitive.
Analytical layer lives in kei-dna-index. Can swap implementations
(naive scan → cached → embeddings) without touching ledger schema.

## kei-fork v0.31.2 — Option D path convention

Moved fork worktree root from `.claude/forks/<id>/` to `_forks/<id>/`.
Reasons:
- `.claude/` is Anthropic-reserved; kit artefacts shouldn't pollute it
- Claude Code sandbox denies Write in `.claude/forks/` for agents
- `_forks/` matches existing kit convention (_primitives/, _roles/,
  _archive/, _blocks/, _capabilities/, _agents/)
- Independent namespace — no coupling to Claude Code internals

13 existing kei-fork tests still pass (they use tempfile kit_roots
so path convention is transparent).

## Usage enabled by these two

- kei-prune can now query "all DNAs in same scope-cluster" → retire dupes
- kei-brain-view can cluster-render instead of tree-render
- Three-role pipeline (writer/auditor/merger) can use precedent() to
  find successful past patterns for same body-hash
- Agents with worktree isolation can write to _forks/ without sandbox
  permission issues
