v0.3.0 — Studio comparisons and cleaner color

Studio frame comparisons caught a color-balancing regression that could paint a dark band into clear sky. This release confines correction to measured overlap, avoids large unsupported arcs and adds a repeatable comparison workflow.

• New a1-stitch compare: mapped reference frames, globally aligned and original views, geometry diagnostics and a review page.
• Experimental --seam adaptive: periodic seam selection with limited spatial and temporal movement. Fixed flow remains default.
• Skip unused lens samples and decode both tracks through one reader. Fixed-flow core benchmarks on an M1 Max were about 15–16% faster at 2K and 4K; this excludes I/O and encoding.
• Updated discoverable agent skill and documented evidence/limits.

Validation: 143 tests, 89% coverage, passing macOS/Linux CI, wheel/sdist builds, and a fresh fully decoded 4K render from an installed wheel outside the checkout. Original-footage comparisons supplement synthetic checks; they do not establish full-motion or whole-image acceptance.

Camera/propeller removal, high-rate gyro fusion, severe occlusion, motion deblurring, GPU execution and log/HDR remain unqualified. No vendor code, masks, models or binaries are included. The project remains alpha.

See measurements and limits and PR #2. Release assets include the wheel, source distribution and SHA-256 checksums; no PyPI publication is implied.
