* Add cross-platform CI test matrix, PyPI classifiers
CI: new test.yml runs lint (ubuntu) + a test matrix (ubuntu/macos/windows
x py3.10/3.12, core+dev, GPU tests skip) on push to main and PRs, closing the
gap where only the release publish.yml ran (ubuntu, no tests). Add PyPI
classifiers (OS/Python/topic). README Tests badge, CLAUDE.md CI note.

* Make availability tests reflect installed deps, not assume gpu extra
The new core+dev CI matrix has no diffusers, so the invisible-engine
availability tests (asserting is_available() is True unconditionally) and the
two mocked invisible CLI tests (whose command gates on is_available before the
mock) failed. Assert availability == actual importability of torch+diffusers,
and patch the CLI availability gate so the mocked-engine tests run regardless of
the gpu extra.

The native-vs-downscale decision in InvisibleEngine.remove_watermark (the
issue #10/#15 fix: max_resolution=0 must not pre-downscale, since any
downscale both loses quality and lets SynthID survive) had no test. Extract
it into a pure helper invisible_engine._target_size(w, h, max_resolution)
and cover it with tests/test_invisible_engine.py::TestTargetSize so a
re-introduced forced downscale fails CI instead of silently regressing #15.
Also:
- Clamp the short side to >=1 in _target_size: extreme aspect ratios (e.g.
5000x3 with --max-resolution 1024) truncated it to 0 and crashed
image.resize(). Pre-existing in the inline math; fixed now that it is a
named, tested function.
- Consolidate the two duplicated temp-file save blocks into one
unconditional save (behavior unchanged: the EXIF-transposed image is
still always persisted before WatermarkRemover reloads it by path), and
drop the now-redundant `_tmp_path is not None` guard in finally.
- Bump version 0.5.3 -> 0.5.4 (pyproject, __init__, uv.lock); document the
helper as the regression guard in CLAUDE.md.

SD-1.5 dreamshaper at 768 px did not defeat SynthID v2 on Gemini 3 Pro
outputs (verified May 2026 via Gemini app's "Verify with SynthID"). Switch
the default invisible engine to SDXL at 1024 px, matching the raiw-app
production config (strength 0.05, steps 50). Drop the SD-1.5 pipeline.
Metadata layer: add C2PA UUID and IPTC AI marker byte-scan detection
across all formats, plus an ISOBMFF box walker (noai/isobmff.py) that
strips top-level C2PA uuid and JUMBF jumb boxes from AVIF/HEIF/JPEG-XL
containers without re-encoding.
README gets a Legal table and a Threat-model section about SynthID v2's
136-bit payload. CLAUDE.md tracks the SD-1.5 regression as historical
context.
