fix: add fallback to find any .tsx/.ts/.circuit.json when no standard entrypoint found

[64johnlee]

Summary

tsci push fails when no index.circuit.tsx (or other standard entrypoint) exists AND no mainEntrypoint is configured in tscircuit.config.json. However, tsci dev finds alternative files — so push should do the same.

Root Cause

push-snippet.ts calls getEntrypoint() and immediately exits if it returns null. Meanwhile, resolve-dev-target.ts has a fallback that uses findSelectableFiles() to locate any .tsx/.ts/.circuit.json file when getEntrypoint() fails.

Fix

Added the same fallback logic to pushSnippet():

if (!snippetFilePath) {
  const fallbackFiles = globbySync(
    ["**/*.tsx", "**/*.ts", "**/*.circuit.json"],
    {
      cwd: process.cwd(),
      ignore: DEFAULT_IGNORED_PATTERNS,
    },
  )
  if (fallbackFiles.length > 0) {
    const fallbackPath = path.resolve(process.cwd(), fallbackFiles[0])
    console.log(kleur.gray(`No standard entrypoint found. Using fallback file: ...`))
    snippetFilePath = fallbackPath
  }
}

This keeps the priority: explicit filePath argument > mainEntrypoint config > standard entrypoint names > fallback to any circuit file.

Testing

• Existing tests pass
• Logic mirrors tsci dev fallback behavior
