--[[ 50-ftdetect.lua — set 'filetype' for cases the built-in detection misses.
Detects bash scripts (a `.bash` extension or a `#!/usr/bin/bash` shebang) and the `claude` CLI
running in a terminal (matched by the command in the `term://<cwd>//<pid>:<command>` buffer name),
the latter tagged `claude-cli` so its terminal can carry Claude-specific ftplugin settings.
