v1.1.0

Four v2 features — job control + observability. Fully backward compatible: the SQLite schema migrates in place on first start (existing jobs default to copies=1, carry no callback, and never re-fire webhooks).

Added

• Job copies — POST /jobs accepts copies (integer 1–100, default 1); the agent prints the job that many times, on every backend (win32print / SumatraPDF / CUPS / raw socket).
• Job cancel — DELETE /jobs/{id} cancels a still-queued job → cancelled (409 once an agent has claimed it — no mid-print interrupt, 404 if unknown). Cancel button on queued rows in the dashboard.
• Webhooks — set a per-job callback_url; the server POSTs the outcome {job_id, state, error, title, printer_id} once the job reaches a terminal state (done / failed / cancelled). Best-effort with retries, at-least-once (make your handler idempotent — dedupe on job_id+state), unsigned, http(s)-only.
• GET /metrics — Prometheus text: printpapi_jobs{state=…} (all five states), printpapi_agents_online / _total, printpapi_printers_total. Client-auth; scrape with a bearer token.

Notes

• 101 tests (was 67), green on Linux + Windows / Python 3.12.
• Each feature was adversarially reviewed; every confirmed finding fixed.
• Docker image built by this release: ghcr.io/lukiprince/printpapi:1.1.0 and :latest (amd64 + arm64).
