CLI produces no output via npx or pnpm (entry guard fails on symlinked paths) #77

Description

Running npx @tanstack/intent@latest list (or install, or any subcommand) produces no output and exits 0 — even when intent-enabled packages with skills are present in node_modules.

The same applies when @tanstack/intent is installed as a local devDependency and invoked via pnpm intent list (which goes through the .bin symlink).

Root cause

The entry guard in dist/cli.mjs (line ~521):

if (process.argv[1] !== void 0 && import.meta.url === pathToFileURL(process.argv[1]).href) {
    const exitCode = await main();
    process.exit(exitCode);
}

When invoked via npx or a pnpm .bin symlink, process.argv[1] resolves to the symlink path while import.meta.url resolves to the real file path. The comparison fails, so main() is never called — the process exits silently with code 0.

Reproduction

# In any project with intent-enabled packages (e.g. @tanstack/db, @tanstack/devtools)
npx @tanstack/intent@latest list
# No output, exit code 0

# Also fails when installed as a devDependency with pnpm:
pnpm add -D @tanstack/intent
pnpm intent list
# No output, exit code 0

Calling main() directly confirms the scanner works fine:

node -e "import('@tanstack/intent/dist/cli.mjs').then(m => m.main(['list']))"
# Correctly outputs: 6 intent-enabled packages, 16 skills (pnpm)

Suggested fix

Use fs.realpathSync to normalize the symlink before comparing:

import { realpathSync } from "node:fs";

const argv1 = process.argv[1];
if (argv1 !== void 0 && import.meta.url === pathToFileURL(realpathSync(argv1)).href) {
    const exitCode = await main();
    process.exit(exitCode);
}
