PowerShell commands lead, bash equivalents in comments: venv
Activate.ps1 + execution-policy note, copy/$env:, a PowerShell
plugin-enable loop, and how the bash naming hook runs under Git Bash
(plus the pre-commit hook catching it automatically). The VS Code
Check task gets a Windows variant (venv\Scripts, bash for the .sh).
Pin shell scripts to LF in .gitattributes so a Windows checkout does
not CRLF-corrupt them into 'bad interpreter' failures.
New docs/DEVELOPMENT-SETUP.md: clone-to-first-change onboarding
(Docker fast path, manual venv+Node daily driver, VS Code, the dev
loop, first-change pointer at the plugin lab, troubleshooting). Ship
.vscode/ launch/tasks/extensions so F5 debugs the backend on 5001 and
a task runs both servers; personal settings.json stays ignored. Fix
the README manual path - it ran the backend on the default 5000, but
the frontend dev server proxies to 5001, so nothing loaded; also add
the plugin upgrade-all step and a VS Code pointer.
