Fix dependency resolution by using version constraints instead of exact pins

[Copilot]

Exact version pinning (==) caused pip's dependency resolver to fail with conflicting requirements. The constraints were over-specified, and mkdocs-plugin-tags==1.0.2 required mkdocs==1.2.3 which conflicted with mkdocs-material>=9.5.

Changes

• Use minimum version constraints (>=) instead of exact pins to allow pip to resolve compatible versions
• Remove mkdocs-plugin-tags - requires incompatible mkdocs version; Material theme has built-in tags support
• Two-step installation - install core packages first, then plugins, to avoid resolution depth issues
• Constrain mike>=2.0 - older versions have Python 3.12 compatibility issues

pip install "mkdocs>=1.5" "mkdocs-material>=9.5"
pip install "mkdocstrings>=0.25" "mkdocstrings-python>=1.9" "mike>=2.0" "mkdocs-autorefs>=1.0" "mkdocs-git-revision-date-localized-plugin>=1.2"

This provides stability through minimum bounds while letting pip handle transitive dependencies.
