fix(docs): fix formatting issues in README.md

- adapt meta-/code-/obs- rules to the local Python benchmark pipeline
- replace db-sql-ddl, code-config-env-scope, test-e2e-pytest with pipeline equivalents
- add code-python-style, data-determinism, data-naming-units, bench-methodology, build-pipeline-tasks
- normalize specs and README typography to ASCII per code-data-formatting
- rewrite root CLAUDE.md trigger table; add .cursorrules and .gitignore
- specs: pipeline plan and task specs 00-11
- rules: 19 binding rule files adapted for this project
- docs: CLAUDE.md rule-trigger table
- config: .cursorrules commit convention, .gitignore excluding out/ and .venv/
- docs: rewrite README.md with pipeline diagrams, setup guide, result placeholders
- config: requirements.txt for the closed dependency list
- datagen: make_lab_config.py writes out/config/lab_config.yaml and .done marker

+# Task 12 — Export: SQLite
+
+## Goal
+Portable single-file SQLite database conforming to the ontology.
+
+## Input
+- `canonical/` snapshot, `schema/ddl_postgresql.sql`.
+
+## Actions
+1. Write `scripts/export_sqlite.py`: translate DDL to SQLite dialect (bigint→INTEGER, timestamptz→TEXT ISO, keep FKs), create `exports/sqlite/labdata.sqlite`.
+2. Bulk-load in dependency order (hierarchy → lookups → headers → points); `executemany` in transactions; create indexes after load; `PRAGMA journal_mode=OFF, synchronous=OFF` during load, `ANALYZE` after.
+3. Load `measurement_types`, `column_definitions`, `instruments` tables; add `lineage` table (row-range level, not per-row, to bound size).
+
+## Intermediate Result (done when)
+- `labdata.sqlite` opens; per-table row counts equal canonical counts; FK integrity check passes (`PRAGMA foreign_key_check` empty).
+- `exports/sqlite/EXPORT_MANIFEST.json` written.
