Subject: [PATCH] fix: dispatch single-file-user-script-init so request hook
 fires

single-file's initUserScriptHandler (in single-file-bootstrap.js) listens
for 'single-file-user-script-init' and only then installs
_singleFile_waitForUserScript.  Without that dispatch our scripts'
'single-file-on-before-capture-request' listeners were never reached,
so neither strip-scripts nor reader-mode Readability applied.

Dispatch the init event at the top of strip-scripts (always present) and
redundantly in READER_MODE_SCRIPT.  Verified end-to-end: artifact for
run_b3181d6d276e4e56a1a6c356ef9bbe8f has
  meta content="applied", max-width:680px CSS, 0 script tags.
