Add dev docs warning banner and RTD version strategy
RTD version setup:
- "stable" = default version users land on (latest non-prerelease tag)
- "latest" = dev docs from master branch (hidden, accessible by URL)
- Tags like v0.9.10 auto-build as versioned releases
Features:
- Dev warning banner shown on /en/latest/ pages via template override
- conf.py detects dev builds from version string or READTHEDOCS_VERSION
- Version switcher enabled in sphinx-rtd-theme
- Document RTD admin settings needed in .readthedocs.yaml comments
