* Read DSH session format v4 written by dsh 0.2.0-rc.2
dsh 0.2.0-rc.2 stamps every session log v4, so discovery skipped each one
and DeepSeek Harness contributed no usage anywhere (#1584).
Admitting v4 only after verifying the reader's whole consumption surface
against DSH's official sessionFormatCatalog (recovery: 'strict',
validation: 'current', @deepseek-ai/dsh-session-format-catalog@0.2.0-rc.2),
per the semantic-update rule docs/providers/dsh.md prescribes for format
bumps: dense seq, usage at assistant/message data.usage (plus a new
informational totalTokens sum) or the embedded stream, tagged end-seed
inheritance, and llm/retry-started attempt slots are all unchanged. What
v4 does change (tool-result role lift, plugin: tag namespacing, surfaceOp
append/replace metadata, new header fields, untagged end-seed markers in
unseeded sessions) is ignored or already handled.
Adds catalog-validated v4 fixtures (same buckets as v0-v3 plus the
informational totalTokens) and extends the per-version parse tests to v4.
Bumps the dsh parse version so cached skip-era sessions recompute.
Verified end to end against a real 0.2.0-rc.2 log: doctor reports the
session readable, and the parsed totals (12 calls, input 11783, output
3699, cache read 107520) match the official catalog artifact exactly.

docs/providers/NEW_PROVIDER.md items the PR had not reached yet, plus the two
surfaces that are functional rather than cosmetic:
- docs/providers/dsh.md and its row in the provider index, documenting the
storage layout, the JSONL-backend-only scope (the opt-in SQLite persistence
backend is not read), and that DSH is a developer preview whose format
version 0 implies no compatibility.
- CHANGELOG entry under Unreleased.
- README provider count 40 -> 41 and a data-locations row.
- app/package.json: $HOME/.dsh in the snap personal-files allowlist, without
which the Linux snap build cannot read DSH sessions at all.
- UsageDataChangeGuard: the DSH sessions root, without which the menubar never
notices a new session and does not refresh.
- Bumps the dsh parse version, since the parser's attribution changed.
