Async on-prem LLM-powered structured information extraction microservice

Adds the transport-agnostic pipeline orchestrator. Each step implements
async validate + process; the runner wraps both in a Timer, writes
per-step entries to response.metadata.timings, and aborts on the first
IXException by writing response.error.
- Step exposes a step_name property (defaults to class name) so tests and
logs label steps consistently.
- Timer is a plain context manager that appends one {step, elapsed_seconds}
entry on exit regardless of whether the body raised, so the timeline
stays reconstructable for failed steps.
- 9 unit tests cover ordering, skip-on-false, IXException in validate vs.
process, timings populated for every executed step, and shared-response
mutation across steps. Non-IX exceptions propagate.

InfoXtractor (ix)
Async, on-prem, LLM-powered structured information extraction microservice.
Given a document (PDF, image, text) and a named use case, ix returns a structured JSON result whose shape matches the use-case schema — together with per-field provenance (OCR segment IDs, bounding boxes, cross-OCR agreement flags) that let the caller decide how much to trust each extracted value.
Status: design phase. Implementation about to start.

Principles
- On-prem always. LLM = Ollama, OCR = local engines (Surya first). No OpenAI / Anthropic / Azure / AWS / cloud.
- Grounded extraction, not DB truth. ix returns best-effort fields + provenance; the caller decides what to trust.
- Transport-agnostic pipeline core. REST + Postgres-queue adapters in parallel on one job store.
