V3 deterministic text/file-count capability pack. By-value connector composition (service_kind=cli, no separate ingredient): one local wc CLI ingredient exposes bounded read-only count metadata for one trusted local path: byte count, line count, word count, character count, longest line, and combined line/word/byte counts. The operations return wc's count output only; they do not return file content, read stdin, accept file lists, recurse directories, follow shell globs, expose arbitrary wc flags, write outputs, use environment overrides, or use a shell wrapper. Editable paths reject flag-like values, URL-like references, and scp-style remotes. Requires a POSIX-compatible wc on PATH. Local and no-egress.
