v1.1.0: extend binary matrix to CPython 3.10/3.11/3.13 on Linux and Windows

- Linux x86_64: add cp310, cp311, cp313 (.so), built in conda-forge envs.
- Windows AMD64: add cp310, cp311, cp313 (.pyd), built with MSVC v14.50.
- All eight binaries verified to produce identical numerical output.
- README compatibility table + build provenance updated.
- macOS still deferred.

+## [1.1.0] - 2026-05-10
+
+Binary matrix expanded to four CPython versions on both supported
+platforms.
+
+### Added
+
+- Pre-compiled Linux x86_64 binaries for **CPython 3.10, 3.11, 3.13**
+  (`sem_core12.cpython-3{10,11,13}-x86_64-linux-gnu.so`).  Built in
+  isolated conda-forge environments with conda-forge gcc, same
+  OpenMP and optimisation flags as the cp312 binary.
+- Pre-compiled Windows AMD64 binaries for **CPython 3.10, 3.11, 3.13**
+  (`sem_core12.cp3{10,11,13}-win_amd64.pyd`).  Built with MSVC v14.50
+  against the matching CPython installed via `winget`.
+
+### Verified
+
+- All eight binaries (4 Linux + 4 Windows) produce identical numerical
+  output for the same fixed-seed input on `batch_max_similarity`.
+
+### Compatibility notes
+
+- macOS is still not provided in this release.  Contact
+  `sales@sevana.biz` if you need a macOS build.
+- numpy requirement unchanged: `numpy >= 1.23`.
