Kevin Veen-Birkenbach 3f30621630 feat(assets): probe-first resolver + SPOT for IMAGE_NAME/PORT + README screenshot
Probe-first asset resolution (regression fix)
---------------------------------------------

cache_manager.cache_file() returned either a relative cache path
(success) or None (failure). The previous app.py fallback
asset['cache'] = cached or asset['source'] mixed both types into
one field, which the template wrapped in url_for('static', ...)
regardless — producing broken
/static/https://file.infinito.nexus/.../logo.png URLs whenever the
source couldn't be downloaded.

- New app/utils/asset_resolver.py: HEAD-probes the URL (3 s
  timeout, image/* content type). On hit, embed directly via a
  new external_url field — no download required. On miss, fall
  back to cache_manager.cache_file. If that also fails, expose
  the source URL via external_url so the browser shows the alt
  text instead of an empty src.
- app.py exposes an asset_src(asset) context processor that
  picks external_url first, then url_for('static', cache),
  so the template never wraps an absolute URL in a static prefix.
- Templates (base, navigation, card) switch to asset_src(...) and
  gate the card image branch on cache or external_url.
- 16 unit tests cover every probe/cache/fallback branch; one live
  integration test exercises the canonical
  https://file.infinito.nexus/assets/img/logo.png to prove the
  probe-first path works end-to-end (cache dir stays empty).
- config.sample.yaml: new Infinito.Nexus card driven by the same
  canonical asset URL.

Single source of truth for IMAGE_NAME and PORT
----------------------------------------------

- env.example is now the only place the literal values live.
- Makefile and docker-compose.yml reference \$(IMAGE_NAME) /
  \${IMAGE_NAME:?…} (same for PORT); no defaults, no silent
  fallbacks.
- New make env / make config bootstrap .env / app/config.yaml
  from their checked-in templates. Idempotent.
- All container-using targets depend on the two bootstrap targets
  so a fresh checkout runs in a single invocation.
- Recipes source .env at recipe-execution time so they pick up a
  freshly bootstrapped .env in the same make invocation.

"""Live network verification of the probe-first asset resolution path.
The unit tests in ``tests/unit/test_asset_resolver.py`` cover every
branch with mocks. This integration test exercises the real
``https://file.infinito.nexus/assets/img/logo.png`` endpoint that
``app/config.sample.yaml`` references for the Infinito.Nexus card. A
green run proves the production resolver behaviour end-to-end:
* probe (HEAD ``image/*``) succeeds against the canonical Infinito.Nexus
asset host, so ``external_url`` is populated directly and **no**
download is performed (the cache directory stays empty).
The download-fallback branch (probe fails → ``cache_manager.cache_file``
serves the asset locally) is intentionally not exercised against a live
endpoint here — it is covered by mocked unit tests because every
candidate "HEAD-fails, GET-succeeds" public URL we tried was flaky
(Nextcloud's ``/download`` endpoint sporadically times out on HEAD even
when GET works), which would make this guard test non-deterministic.
