grepxcel 0.1.1

Features

• --strict mode — grepxcel extract --strict exits with code 2 if any
  field has extraction issues (validation mismatch, missing anchor, empty value).
  Lists the affected field names on stderr. Use in pipelines to catch incomplete
  extractions that would otherwise exit 0 or 1 silently.
• quickstart command — grepxcel quickstart prints a guided tutorial in
  your terminal: what grepxcel does, how to create your first pattern, and how
  to run your first extraction. No files created or modified.

Documentation

• README rewritten — shorter, friendlier, focused on non-technical users.
  Full CLI reference moved to docs/cli-reference.md.
• docs/cli-reference.md — comprehensive reference for all CLI commands,
  flags, backends, and logging model (moved from README).
• Removed absolute correctness claims ("never silently wrong") — replaced with
  honest language about the tool's design intent and pattern-dependent quality.
• All README links now absolute GitHub URLs so they resolve on PyPI.
