`suggest.Closest` ranks flag/command suggestions by shared prefix then edit
distance. A hallucinated name welded from two real names -- e.g. `--sql-file`
from the real `--sql` and `--file` of `apps +db-execute` -- defeats both
signals: the leading half wins on prefix, and the trailing half (`file`, 4
edits from `sql-file`, budget 2) is dropped. The hint then names the flag the
caller did not want and omits the one that does exactly what they asked for.
The cost is not the rejected call. Steered to `--sql`, callers inline SQL
through the shell, where quoting mangles `DEFAULT ''` and
`current_setting(...)` into syntax errors that read as SQL-authoring bugs.
`--file` passes file contents verbatim and avoids that class entirely.
Treat a candidate that exactly equals one hyphen-delimited segment of the typed
name as plausible, however far the whole string drifted. Ranking is unchanged --
segment hits are admitted, not promoted -- so the leading segment still ranks
first, and an unrelated candidate list still yields no suggestions.
