v0.1.0

First working release. Pre-1.0, so the API and profile schema may still change in a minor
release.

Added

• Profile-driven domain model: a Markdown profile with YAML front matter drives scoring,
  eligibility, and relevance; nothing candidate-specific is hardcoded.
• Hexagonal architecture (domain, application, infrastructure) with the dependency direction
  enforced by a test.
• Source adapters behind a JobSource port: Himalayas (structured eligibility hints) and RemoteOK
  (text-fallback eligibility), registered through an open/closed registry.
• The combination pipeline: fan out sources concurrently, dedupe the same posting across boards,
  score against the profile, classify eligibility, filter by relevance, and rank by fit.
• A country-to-region map so a profile region (latam) accepts a board's country restriction
  (Brazil).
• Three-state eligibility hints (unknown / unrestricted / restricted) and honest per-source
  coverage, so a partial run is never mistaken for a complete one.
• job-seeker CLI (find, sources) with JSON, CSV, and self-contained HTML reports.
• MCP server exposing find_jobs, list_sources, and describe_engine to a local agent.
