All MCP server run.sh scripts now capture the original working
directory as CLAUDE_PROJECT_DIR before changing to the script
directory. This fixes the branch detection issue where MCP tools
detected the plugin repo's branch instead of the user's project branch.
This is a follow-up fix to #231 - the original fix relied on
CLAUDE_PROJECT_DIR being set by Claude Code, but it isn't.
Now we capture it ourselves from PWD at startup time.
Closes#231 (proper fix)
