popovskikandClaude Opus 4.8 2d535db7d5 feat(cms): U4 one-command site build + local preview
Add tools/build_site.py: runs the full pipeline in dependency order
(build_content -> build_listings -> seo_inject --all --sitemap ->
build_botlinks -> build_search_index), each as a subprocess so a failing
step aborts the build before anything downstream runs (no partial
deploy). --check verifies non-destructively; --images also runs
optimize_images. This is what CI will run in U5.

Fix a build_content idempotence bug found via U4: the hero and
article-header regions were emitted with leading indentation while the
regex left the template's pre-tag whitespace in place, so indentation
compounded (+16 spaces) on every rebuild. First line is now unindented;
the full build is verified idempotent (identical git tree across two
runs). Added a fixpoint test (re-rendering a page's own output is
byte-identical) so this can't regress.

docs/local-preview.md: build + serve on :8000 in all three languages.
tools/README.md: document build_site + build_content.

26 tests pass.

Characterization tests for tools/build_content.py (U2).
The core guarantee (plan R5): rendering every content/ entry reproduces the
CURRENT live detail page, compared semantically (whitespace- and
attribute-order-insensitive). This is what protects against SEO/layout
regressions when the build takes over page generation.
Run directly: python tools/tests/test_build_content.py
Or with pytest: pytest tools/tests/test_build_content.py
