engine — Recon V2 generic rule-engine interpreter.

Replaces the per-type matchers (matchers/*.py) with one execution path driven
entirely by data:

  source templates  (docs/contracts/recon_source_template_schema.json)
      → loader.load_source: parse + normalize a file into canonical fields
  rule sets         (docs/contracts/recon_rule_schema.json)
      → pipeline.run: chained stages, each a tiered one-to-one match

No business vocabulary (HIS/hospital/unit) appears anywhere in this package.
