review pass: shoulder edge-state in menus; release-notes asset names

Two defects found in the local review of the unpushed v0.2.0-pre work:

1. input.c: padShoulderPrev was only updated outside menu mode, so a
   shoulder held across the menu->game transition fired a spurious
   weapon cycle on the first gameplay poll. Edge state is now tracked
   every poll; emission stays suppressed in menus where A means select.

2. ci.yml release job: the notes template substitutes <version> with the
   raw tag (v0.2.0-pre), but bundle-{linux,win}.sh strip the leading v
   when building asset names -- the published notes would have linked
   goldeneye-pc-port-v0.2.0-pre-* assets that don't exist. Substitute
   the stripped form (NOTES_VERSION) instead.
