V3 deterministic PDF text-search capability pack. By-value connector composition (service_kind=cli, no separate ingredient): the local pdfgrep CLI exposes readiness, bounded page-numbered PDF text search, fixed-string search, case-insensitive search, context search, match-only extraction, total match counts, and page-level match counts for one trusted local PDF path. This pack deliberately exposes bounded path-based value output rather than file_ref materialization, because matched PDF text is returned on stdout. No arbitrary pdfgrep flags, recursive directory search, password arguments, pattern-file inputs, cache writes, debug output, shell wrapper, stdin, or multi-file glob search are exposed, and exit code 1 (no matches) is treated as success for search/count operations. Requires pdfgrep on PATH (Debian/Ubuntu: apt install pdfgrep). Local and no-egress.
