fix(patches): make livefetch handle both original and retry-patched code

The retry and livefetch patches both target the same upstream code block.
If retry runs first (current postinstall order), it transforms the code
into a variant that livefetch couldn't match — silently losing the
"always fetch live page" behavior. Now livefetch detects both the
original upstream code and the retry-patched variant.
