fixes #173

PR Overview

This PR fixes shell detection issues on Windows by ensuring GitBash paths use forward slashes and refactors fallback order for shell detection. Key changes include:

• Adding unit tests for various shell types.
• Updating the GitBash regex in shellDetector to cover additional patterns.
• Replacing unsafeEntries usage with a new _entries function in shellDetector.
• Refactoring Venv and Conda utility modules to include a pathForGitBash helper that replaces backslashes.
• Removing the now redundant unsafeEntries utility file.

Changes

src/test/features/common/shellDetector.unit.test.ts	Added tests for multiple shell types with a check to skip “unknown” shells
src/features/common/shellDetector.ts	Updated GitBash regex, replaced unsafeEntries with _entries, and reordered shell detection fallbacks
src/managers/builtin/venvUtils.ts	Refactored Venv command mappings using a new pathForGitBash helper and modernized the code style
src/managers/conda/condaUtils.ts	Added GitBash-specific shell activation/deactivation using pathForGitBash and updated environment creation logic

• Ensure that comparing the test string 'unknown' to TerminalShellType.unknown is type-safe; verify that both values are compatible (e.g., if TerminalShellType.unknown is a string literal) to avoid unexpected mismatches.

if (shellType === TerminalShellType.unknown) {

• Review the reordering of fallback detection functions; using identifyShellFromVSC before identifyShellFromTerminalName may change the intended detection logic—ensure this new order still meets all edge cases.

shellType = identifyShellFromVSC(terminal);
