/**
 * The Stirling operation library.
 *
 * Three layers, ported faithfully from the prototype:
 *
 *  1. PIPELINE_OPS — the canonical pipeline-stage taxonomy. Ops are grouped
 *     by `OpKind` (ingest / validate / modify / secure / store / alert) which
 *     drives accent colours in chip rendering.
 *
 *  2. LIBRARY_OPS — the broader catalogue surfaced in the composer's
 *     Operations picker. Includes everything in PIPELINE_OPS plus the wider
 *     PDF tool set (formatting, extraction, AI-powered ops, schema-aware
 *     ops). Each library op also carries an `OpCategory` for finer-grained
 *     grouping in the picker UI.
 *
 *  3. PIPELINE_AGENTS — one-click bundles of related ops (PII Sweep, Trust &
 *     Verify, Compliance Pack, Format Prep). Selecting an agent expands its
 *     `ops` list into the chip row.
 *
 * SOURCE_OPTIONS and DESTINATION_OPTIONS sit alongside as the structural
 * rails — every pipeline has exactly one source and one destination.
