✨ feat(sdk): add environment detection and dynamic icons for PyCharm 2026.1

PyCharm 2026.1 removed the generic Virtualenv icon and now requires proper SDK flavor data to display environment-specific icons (UV, Poetry, Hatch, Conda, Pipenv). Without this, all environments showed broken icon references and package managers couldn't properly detect their tooling.

The plugin now detects environment types by checking filesystem markers: pyvenv.cfg for UV, conda-meta directories for Conda, .gitignore markers for Hatch, and standard cache locations (with environment variable overrides) for Poetry and Pipenv. Each detected type gets the appropriate SDK flavor data so PyCharm's package managers work correctly and display the right icons.

SDK creation now properly handles PyCharm's threading model by separating name generation (which runs Python) from write-locked modifications. Only in-project virtual environments get associated with the project to avoid polluting other projects' interpreter lists.

+- Support for configurable environment paths via environment variables (HATCH_DATA_DIR, WORKON_HOME, etc.)
+- Comprehensive logging for environment detection debugging
+
+### Changed
+
+- Updated to PyCharm 2026.1 platform API
+- Minimum supported version is now PyCharm 2026.1 (build 261)
+- Removed module-level interpreter action (kept project-level only)

+- Environment detection checks pyvenv.cfg for UV marker, .gitignore for Hatch marker, and standard cache locations
+
+### Fixed
+

 ## Features
 
 - **Quick interpreter switching**: Right-click any virtual environment folder to set it as your project or module
   interpreter instantly
-- **Visual identification**: Virtual environment folders display with a distinctive icon and customizable decoration
-  (e.g., `.venv [3.11.5 - CPython]`) in the project view
+- **Smart environment detection**: Automatically detects environment types (UV, Conda, Poetry, Hatch, Pipenv,
+  virtualenv) and sets appropriate metadata and icons
+- **Dynamic icons**: Tree view and context menus display environment-specific icons (UV, Conda, Poetry, Hatch, Pipenv)
+  based on detection
+- **Visual identification**: Virtual environment folders display with customizable decoration (e.g.,
+  `.venv [3.11.5 - CPython]`) in the project view
 - **Customizable decorations**: Configure which fields to show (Python version, implementation, system site-packages,
   creator tool), their order, and the format via Settings
 - **Multi-IDE support**: Works with PyCharm (Community and Professional), IntelliJ IDEA, GoLand, CLion, and RustRover
-- **Smart detection**: Automatically detects Python virtual environments by recognizing `pyvenv.cfg` files
+- **Smart association**: In-project virtual environments are associated with the current project; external environments
+  (Poetry cache, Hatch cache, Pipenv virtualenvs) remain global
 - **Cached version display**: Python version information is cached for performance and automatically refreshed when
   `pyvenv.cfg` files change
