The home server's Ollama doesn't have gpt-oss:20b pulled; qwen3:14b is
already there and is what mammon's chat agent uses. Switching the default
now so the first deploy passes the /healthz ollama probe without an extra
`ollama pull` step. The spec lists gpt-oss:20b as a concrete example;
qwen3:14b is equally on-prem and Ollama-structured-output-compatible.
Touched: AppConfig default, BankStatementHeader Request.default_model,
.env.example, setup_server.sh ollama-list check, AGENTS.md, deployment.md,
live tests. Unit tests that hard-coded the old model string but don't
assert the default were left alone.
Also: ASCII en-dash in e2e_smoke.py Paperless-style text (ruff RUF001).

Real GenAIClient for the production pipeline. Sends `format=<pydantic JSON
schema>`, `stream=false`, and mapped options (`temperature`; drops
`reasoning_effort`). Content-parts lists joined to a single string since
MVP models don't speak native content-parts. Error mapping per spec:
connection/timeout/5xx → IX_002_000, schema violations → IX_002_001.
`selfcheck()` probes /api/tags with a fixed 5 s timeout for /healthz.
Tests: 10 hermetic pytest-httpx unit tests; 2 live tests gated on
IX_TEST_OLLAMA=1 (never run in CI).
