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

+# 05 - Convert to SQLite (optimized)
+
+## Context / Goal
+Build the single-file relational variant optimized for size and single-user query speed.
+
+## Dependencies
+03.
+
+## Input
+CSV tree.
+
+## Processing instructions
+- One database `./out/sqlite/tribo.db`. PRAGMAs during load: `journal_mode=OFF, synchronous=OFF, cache_size=-262144`; after load: `journal_mode=WAL`, `ANALYZE`, `VACUUM`.
+- Schema (16-table style, integer surrogate keys everywhere; no TEXT foreign keys in bulk tables):
+	- `batches, wafers, coupons, runs, instruments, tracks` - dimension tables, TEXT natural keys kept as unique columns.
+	- `xrf_points(coupon_id INT, gx INT, gy INT, pt_wtpct REAL, au_wtpct REAL)`.
+	- `profilometry_points(coupon_id INT, gx INT, gy INT, thickness_um REAL)`.
+	- `nanoindentation(coupon_id INT, indent_id INT, x_um REAL, y_um REAL, hardness_gpa REAL, reduced_modulus_gpa REAL)`.
+	- `afm(coupon_id INT PRIMARY KEY, ra_nm REAL, rq_nm REAL)`.
+	- `friction_cycles(track_id INT, cycle INT, cof REAL, PRIMARY KEY(track_id, cycle)) WITHOUT ROWID`.
+	- `friction_loop_points(track_id INT, cycle INT, pt INT, position_um REAL, force_mn REAL, PRIMARY KEY(track_id, cycle, pt)) WITHOUT ROWID`.
+	- `wear(track_id INT PRIMARY KEY, wear_volume_um3 REAL, k_archard REAL, sliding_distance_m REAL)`.
+	- `track_summary(track_id INT PRIMARY KEY, cof_ss_mean REAL, cof_ss_std REAL, run_in_cycles INT)` - precomputed during load.
+- Indexes for Q1-Q7: `coupons(au_wtpct_mean)`, `tracks(run_id)`, `tracks(coupon_id)`, `runs(environment)`, composite `tracks(environment, load_mn)` (denormalize environment/load onto tracks).
+- Batch inserts with `executemany`, 50k rows per transaction.
+- Validate row counts against MANIFEST.
+
+## Output
+- `./out/sqlite/tribo.db`; size appended to `storage_sizes.csv`.
+- Marker `./out/.done/05.ok`.
