feat(grep): add distinguishing title to grep and glob tool blocks

grep: pattern (glob) in path (e.g. "foo (*.ts) in /src")
glob: pattern in dir (e.g. "**/*.ts in /src")

Previously both hardcoded title:"", making multiple concurrent
calls in the same turn visually identical in opencode's tool blocks.

Passes args through the already-supported result(value, args)
signature; no interface changes needed.
