fix(npm): install the binary on first run when postinstall was skipped

Browse source 
npm 12 blocks install scripts of unapproved packages under `npx` and
`npm install -g` (its allow-scripts policy). The postinstall download never
ran, so `npx -y idx-mcp` exited with "installed binary not found" and MCP
clients saw only "Connection closed". Hermes Agent hits this by default: it
runs a bare `npx` with its own npm 12.

The launcher now runs the installer itself when the binary is missing,
logging to stderr so the idx-mcp stdout channel stays clean. This also covers
pnpm 10+ and bun, which skip dependency scripts by default.

npm-smoke installs idx-mcp with --ignore-scripts and checks that the first
run still starts cleanly.

Fixes #41
