refactor: remove package-level caching to support dynamic installation

Remove package-level caching in cnr_utils and node_package modules to enable
proper dynamic custom node installation and version switching without ComfyUI
server restarts.

Key Changes:
- Remove @lru_cache decorators from version-sensitive functions
- Remove cached_property from NodePackage for dynamic state updates
- Add comprehensive test suite with parallel execution support
- Implement version switching tests (CNR ↔ Nightly)
- Add case sensitivity integration tests
- Improve error handling and logging

API Priority Rules (manager_core.py:1801):
- Enabled-Priority: Show only enabled version when both exist
- CNR-Priority: Show only CNR when both CNR and Nightly are disabled
- Prevents duplicate package entries in /v2/customnode/installed API
- Cross-match using cnr_id and aux_id for CNR ↔ Nightly detection

Test Infrastructure:
- 8 test files with 59 comprehensive test cases
- Parallel test execution across 5 isolated environments
- Automated test scripts with environment setup
- Configurable timeout (60 minutes default)
- Support for both master and dr-support-pip-cm branches

Bug Fixes:
- Fix COMFYUI_CUSTOM_NODES_PATH environment variable export
- Resolve test fixture regression with module-level variables
- Fix import timing issues in test configuration
- Register pytest integration marker to eliminate warnings
- Fix POSIX compliance in shell scripts (((var++)) → $((var + 1)))

Documentation:
- CNR_VERSION_MANAGEMENT_DESIGN.md v1.0 → v1.1 with API priority rules
- Add test guides and execution documentation (TESTING_PROMPT.md)
- Add security-enhanced installation guide
- Create CLI migration guides and references
- Document package version management
