add doctor command, fix ISBN false positives, wire up CI

ISBN regex now requires an explicit prefix, so it stops matching
years, URLs, job IDs, and dilution ratios.

doctor checks the environment end to end: Python, Tesseract,
PaddleOCR, the PyTorch backend, table/figure detectors, scispaCy,
config, DB, output.

CI runs on 2 OS x 3 Python versions plus a doctor smoke job.

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+### Added
+- `init` command: writes a minimal `config.yaml` with platform-correct defaults and checks for Tesseract.
+- `demo` command: runs the pipeline on a bundled sample screenshot, prints the output Markdown, and verifies the install in <30s.
+- `setup [basic|full]` command: executes install steps with confirmation (`--yes`/`--dry-run`).
+- `doctor` command: health check for Python, Tesseract, PaddleOCR, PyTorch backend, table/figure detectors, scispaCy model, config, database, and output directory.
+- Lazy settings: `settings` is a proxy; importing the package no longer reads `config.yaml` from cwd.
+- Config search paths: `$OCR_PIPELINE_CONFIG` → `./config.yaml` → per-user config dir.
+- Optional dependency extras: `paddle`, `tables`, `figures`, `scientific`, `kg`, `full`.
+- Engine-aware preprocessing: PaddleOCR reads the (size-capped) original image; Tesseract reads the binarized derivative. Fixes dark-mode OCR quality (confidence 0.83 → 0.95 on test screenshots).
+- `data/test_run_full` sample run on 7 screenshots demonstrating full-stack output.
+- Tests for citations (19), doctor (15), and startup (12).
+
+### Changed
+- Code defaults are now safe: Tesseract OCR, detectors/entities off. The repo's `config.yaml` keeps the full stack for development.
+- Detectors default to `enabled: false`; enable per-detector in your config.
+- OCR engine default is now `tesseract` (was `paddleocr`).
+- `run` results table now shows Skipped count.
+- Run directories are created lazily on first write (no empty `run_NNN`).
+- `kg_ocr` package marked experimental; deps under `--extra kg`, helpful ImportError on bare import.
+
+### Fixed
+- ISBN regex no longer false-positives on years, URLs, job IDs, or dilutions. Now requires an explicit `ISBN` prefix and matches strict 13- or 10-digit structures.
+- `opencv-python-headless` pinned to `<5.0.0`; the 5.0 wheel did not ship a working `cv2` module on Python 3.13.
+- `import ocr_pipeline` no longer depends on the caller's cwd.
+
+### Removed
+- Unused core dependencies: `tqdm`, `scikit-image`, `sqlite-utils`, `xxhash`, `python-slugify`, `python-magic`, `legacy-cgi`.
+- Core dependency on `spacy` (moved to `scientific` extra).
+- Core dependency on `paddleocr`/`paddlepaddle` (moved to `paddle` extra).
+- Core dependency on `torch`/`torchvision`/`transformers`/`timm` (moved to `tables` extra).
+- Core dependency on `layoutparser` (moved to `figures` extra).
+
+## [0.1.0] - Initial
+
+Initial release with PaddleOCR + Tesseract fallback, scispaCy NER, layout-aware detectors, citation matching, and Markdown output with YAML frontmatter.
