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 01 — Setup Workspace
+
+## Goal
+Create the working directory layout and versioned pipeline configuration.
+
+## Input
+- Path to the raw CSV root (read-only). Ask the user if unknown.
+
+## Actions
+1. Create:
+```
+work/
+	config/          # pipeline.json, token_patterns.json, column_mappings/, anomaly_rules.json
+	manifest/        # inventory, fingerprints, reports
+	canonical/       # cleansed partitioned dataset
+	rejects/         # quarantined anomalies
+	schema/          # DDL, data dictionary, instruments repository
+	exports/{json,sqlite,postgresql,rdf}/
+	lineage/
+	scripts/         # all Python scripts produced by tasks
+```
+2. Write `work/config/pipeline.json`: `SOURCE_ROOT`, sample sizes (head/tail/random rows), version stamp.
+3. Write empty `work/config/token_patterns.json` and `work/config/anomaly_rules.json` skeletons.
+
+## Intermediate Result (done when)
+- Directory tree exists; `pipeline.json` valid and points to an existing `SOURCE_ROOT`.
