Hardcoded platform check forced PowerShell env syntax on Windows
regardless of the actual shell. Replaced with detectShellType() so
Git Bash, WSL, and similar environments use unix prefixes while
native PowerShell continues to get powershell prefixes.

The non-interactive-env hook hardcoded shellType as 'unix', causing
'export' syntax to be used on Windows PowerShell where it doesn't work.
This caused sub-agent infinite loops on Windows as git commands would
fail with 'export: The term export is not recognized' and retry forever.
Fix: use the existing detectShellType() function which correctly detects
PowerShell (via PSModulePath), csh, cmd (win32 fallback), and unix shells.
Updated tests to verify platform-aware shell syntax selection.
Closes#3000
- Delete PSModulePath in beforeEach() to prevent CI cross-platform detection
- Set SHELL=/bin/bash to ensure tests start with clean Unix-like environment
- Fixes flaky test failures on GitHub Actions CI runners
- Tests can still override these values for PowerShell-specific behavior
Previous `VAR=val cmd` format only applied to first command in chains.
New `export VAR=val; cmd` format ensures variables persist for all commands.
Also increased test timeouts for todo-continuation-enforcer stability.

OpenCode's bash tool ignores args.env and uses hardcoded process.env in spawn().
Work around this by prepending GIT_EDITOR, EDITOR, VISUAL, and PAGER env vars
directly to the command string. Only applies to git commands to avoid bloating
non-git commands.
Added shellEscape() and buildEnvPrefix() helper functions to properly escape
env var values and construct the prefix string.
