chore: contributor workflow — issue/PR templates, git-cliff, gitea-workflow doc (refs #31)

Add the Gitea issue templates (slice/bug/adr-proposal) and a PR template
that carry the Definition of Done, a git-cliff config (cliff.toml) with a
`make changelog` target, the generated CHANGELOG.md, and docs/gitea-
workflow.md documenting the issue -> milestone -> PR flow.

Verified: make lint/build/unit green; `make changelog` regenerates the
changelog from Conventional Commits.

-# ADR-0001: Loose coupling to upstream Common Ground modules
-
-- **Status:** Accepted
-- **Date:** 2026-06-03
-- **Deciders:** Respellion engineering
-- **Template note:** This is the first ADR and doubles as the worked example of
-  the Nygard template. Copy its shape for new ADRs (`adr-NNNN-title.md`).
-
-## Context
-
-This reference application orchestrates several upstream Common Ground modules —
-OpenZaak (ZGW APIs), Open Notificaties (NRC), Objecten/Objecttypen, Flowable,
-Keycloak. Each is an independently developed, independently deployed peer. The
-temptation in a demo is to reach straight into a peer's database or couple to its
-internal schema to move faster. That coupling is exactly what makes Common Ground
-landscapes brittle and un-upgradeable in practice.
-
-We need a stance, recorded up front, on how our services may talk to these peers.
-
-## Decision
-
-**We integrate with upstream modules only through their documented public APIs, and
-we isolate that integration behind explicit anti-corruption boundaries.**
-
-Concretely (mirrors CLAUDE.md §8):
-
-1. The **ACL** is the only code that talks to ZGW APIs; no other service constructs
-   ZGW URLs.
-2. The **Workflow Client** is the only code that talks to Flowable; BPMN models hold
-   no OpenZaak knowledge.
-3. **Portals talk only to the BFF** — never directly to a backend or a peer module.
-4. **No direct database access across services or to any peer.** Each service owns
-   its schema; the Read Projection is a rebuildable derived artefact.
-5. **Idempotency at every event boundary** (the Event Subscriber tolerates duplicate
-   and out-of-order NRC events).
-
-Bending any of these is an ADR-worthy moment (CLAUDE.md §14): stop and open an
-`adr-proposal` issue first.
-
-## Consequences
-
-**Positive**
-
-- Upstream modules can be upgraded or swapped behind their APIs without rippling
-  through our services.
-- Coupling is visible and minimal — anti-corruption code lives in one named place.
-- The architecture teaches the Common Ground pattern by enforcing it.
-
-**Negative / costs**
-
-- More indirection: a translation layer (ACL, Workflow Client) instead of direct
-  calls. Accepted — it's the point.
-- Eventual consistency across aggregates must be designed for, not assumed away.
-
-**Follow-up**
-
-- Each integration slice that touches a boundary references this ADR; new boundary
-  decisions get their own ADR.

-## Where to go
-
-- **[Product Requirements](PRD.md)** — what we're building and why.
-- **[ADR-0001: Loose coupling](architecture/adr-0001-loose-coupling.md)** — the
-  non-negotiable integration stance; the template for future ADRs.
-- **[Working in Gitea](gitea-workflow.md)** — issues, milestones, branches, PRs.
-- **[CI runbook](runbooks/ci.md)** — the pipeline and the `make ci` local gate.
-
-## Quickstart
-
-See the repository `README.md`. In short: clone, then either run the checks with
-`make ci`, or bring the BFF up with
-`docker compose -f infra/docker-compose.yml up -d --build --wait` and
-`curl http://localhost:8080/health`.
