Fix python 314 compat (#520)

Fix python 3.14 build compat

1. `pyo3` depend updated to `0.26`: this is required or else it can't be
compiled for python 3.14
2. version update to `1.1.11-dev0`
```
# removed
Fix compat with Rustc 1.86.0
3. change rust conditions that was throwing `unstable` `errors` in `rustc 1.86.0 (05f9846f8 2025-03-31)` (fairly new version, not the latest) _
```
