fix: remove unnecessary try/catch blocks in framenavigated handler

- storeAvailable: evaluate() always succeeds after framenavigated
  because Puppeteer waits for the execution context automatically
  (verified via CDP event order and Puppeteer source)
- inject(): matches upstream behavior - let errors surface instead
  of silently swallowing them
