v0.6.0 — polish + developer ergonomics

A grab-bag of improvements that make AgentGate easier to install, debug, lint, and ship.

agentgate doctor — one command prints Python version, deps, optional tools, notification channel config, port availability, and policy validation. The first thing a new user should run.
agentgate lint policy.yaml — catches duplicate rule IDs, deny rules without a reason, empty match blocks, dead _glob/_regex keys. --strict turns warnings into errors.
agentgate stats --by-source / --by-rule — break down the audit log by where events came from (claude-code, proxy, manual) or which rule fired.
/api/events?action=...&source=...&since=...&limit=... — the dashboard's JSON API now accepts filters so CI / monitoring tools can query exactly the rows they want.
docs/architecture.md — a Mermaid-rendered map of every component, plus sequence diagrams for the deny and ask round-trip flows.
docs/dashboard.svg — inline-rendered dashboard preview in README.md (works without JavaScript, no external assets).
Makefile — make install / test / verify / lint / format / build / publish / release / clean / doctor / run-dashboard / run-proxy / run-approval.
.devcontainer/devcontainer.json — one-click dev environment in GitHub Codespaces or VS Code Remote.
Windows paths — the file-fallback and approval DB paths now use tempfile.gettempdir() instead of hard-coded /tmp/. Tests updated to use AGENTGATE_ASK_FALLBACK.
CONTRIBUTING.md — full release flow (bump, build, publish to PyPI, verify install, tag, GitHub release).

83 → 90 unit tests (+7 for doctor + lint). All 90 pass; 10/10 e2e verify steps still green; CI green on Py 3.12 + 3.13.
