/**
 * Fish completion generator. Fish has the cleanest completion grammar of the
 * three shells: one `complete` line per option per command. No driver function
 * needed; fish's built-in `__fish_seen_subcommand_from` and friends do the
 * subcommand parsing for us. The bin name is injected by the caller.
 *
 * Layout per command path:
 *   complete -c <bin> -n '<condition>' -a <subcommand> -d '<description>'
 *   complete -c <bin> -n '<condition>' -l <long> [-s <short>] -d '<description>' [-r] [-x] [-a '<choices>']
 *
 * Dynamic values: fish runs the command in `-a '(...)'` at completion time,
 * giving us per-tab callbacks for free.

/**
 * DYNAMIC fish completion: a thin, tree-independent shim that calls
 * `<bin> __complete-line` on every <Tab> (see bash.ts generateBashDynamic for
 * the rationale). Fish renders `value\tdescription` lines natively, so the
 * helper just strips the trailing `\x1f:<n>` directive line. Note: fish's
 * declarative `complete -a` cannot switch to file completion from inside the
 * helper, so the File directive is a no-op here — use static fish completion
 * (`completion fish`) if you need file fallback on a path-valued positional.
