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 02 — Filesystem Inventory
+
+## Goal
+Non-destructive inventory of every file under `SOURCE_ROOT`.
+
+## Input
+- `work/config/pipeline.json` (Task 01).
+
+## Actions
+1. Write `scripts/fs_inventory.py` (streaming walk, constant memory).
+2. For each file capture: relative path, path components (folder tokens), filename, extension, size bytes, mtime (ISO), sha-free quick id (path hash).
+3. Emit `manifest/inventory.jsonl` (one JSON object per file) and load an index copy into `manifest/manifest.sqlite` table `inventory`.
+4. Emit `manifest/inventory_summary.md`: file count, total size, count by extension, count and size by top-level folder, depth histogram.
+
+## Intermediate Result (done when)
+- `inventory.jsonl` row count == filesystem file count.
+- `inventory_summary.md` produced; non-CSV extensions listed explicitly.
