#218 docs(changelog): record the CLI JSON output and docs merged since v0.17.0

What this PR does

Six PRs landed after the v0.17.0 release — [#207], [#208], [#209], [#210], [#216] — and none of them touched CHANGELOG.md. The machine-readable CLI surface and the two new reference docs were missing from the shipped history entirely.

Adds an ## Unreleased (merged since v0.17.0) section above ## Shipped, covering:

• scan --json, doctor --json, policy-history --json, log --jsonl
• scan --quiet
• docs/CLI.md and docs/REASON_CODES.md

Contributors are credited by handle and PR number, and the entries link the issues each closed (#185, [#186], [#187]).

Why a new section rather than appending to ## Shipped

## Shipped reads as released history, and the intro names v0.17.0 as the latest release. Appending there would present unreleased work as shipped. These bullets fold into ## Shipped when the next version is cut.

Verification

Every claim was checked against source on main rather than taken from the PR titles:

• all five flags exist — src/doberman/cli/main.py:210 (--quiet), :216 (scan --json), :534 (doctor --json), :779 (log --jsonl), :979 (policy-history --json)
• the documented (category, name) scan ordering matches main.py:239
• the JSONL allowlist claim matches _JSONL_EXTRA_COLUMNS at main.py:770
• docs/REASON_CODES.md has exactly 51 rows against 51 ReasonCode members

The scan --quiet entry deliberately notes that scan exits 0 regardless of findings, with a pointer to [#193] — the help text implies CI gating that does not exist yet, and the changelog shouldn't repeat that implication.

Tests added (run in CI)

None — documentation only, no behavior change.

Security checklist

• [x] Fails closed on error / uncertainty — n/a, no code change
• [x] No secret, full file, or unredacted prompt logged or committed
• [x] Any guardrail/learning change is raise-only (no silent loosening) — n/a
• [x] Every BLOCK/AUTH carries reason codes + a human explanation — n/a

Risks introduced

None. Docs-only.
