Fixes#993 (Permission denied on hook scripts) without relying on
client-side +x preservation.
The hook executor spawns commands via /bin/sh -c, which requires +x
to execute a script directly. Prefixing with bash reads the script
as data — mode bits are irrelevant. This works on all Claude Code
versions, whereas the client-side chmod fix (claude-cli #24666) only
shipped in v2.1.86.
All 3 scripts declare #!/bin/bash and use bashisms ([[ ]], =~), so
bash (not sh) is the correct interpreter.
The version field forces a fresh cache path (1.0.0/ instead of
unknown/), ensuring the new hooks.json reaches users with stale
caches.
