Michael abb720997e docs: tight, scannable rewrite — every item earns its place
Refactors all 10 docs (README, USER-GUIDE, CLI-REFERENCE, REQUIREMENTS,
TECHNICAL, DEVELOPER, BUSINESS, DECISIONS, RECOVERY, docs/README) from
prose-heavy to bullet-heavy + table-heavy. Same information density,
significantly less reading load.

Net: 2600 → 1652 lines (~37% reduction) WHILE adding the new content
that landed since v1.6:

- Format Standardizer (3rd Ready tool)
- 199-row buyer corpus
- src/core/errors.py structured hierarchy + ensure_dataframe /
  ensure_choice / wrap_file_read|write / format_for_user helpers
- src/core/_constants.py shared USPS/state lookup tables
- Cross-tool audit fixes (NaN matching, removed_df schema, validation,
  enum-bounds checks, forward-compat config)
- Per-domain error_policy across format standardizers
- Inconsistent-date-format detector
- Excel header-row auto-detection + write_file delimiter param

Per-doc changes:

- README.md (175 → 71): 9-tool table at top, status column, 3 CLI
  entry points listed, dropped repeated marketing prose.
- docs/README.md (38 → 27): pure index — buyer-facing vs creator-only
  split + version footer.
- USER-GUIDE.md (208 → 118): tool table replaces script descriptions,
  troubleshooting compressed to bullets, gate explanation tightened.
- CLI-REFERENCE.md (451 → 235): collapsed flag tables, removed
  redundant intro text, kept full recipes section.
- REQUIREMENTS.md (146 → 129): 18 numbered sections (was 17), added
  §18 Error Handling, formatting tightened to single-line entries.
- TECHNICAL.md (570 → 350): collapsed §3 build pipeline tables, merged
  redundant §3.5-3.7 OS sections, added §7 (Error handling) +
  §11.3 (Format Standardizer spec) + §11.4-11.7 (analyzer / gate /
  Review page / repair_bytes promoted from §10.2.x sub-numbering).
- DEVELOPER.md (285 → 161): module map table replaces per-file prose,
  extension recipes condensed, new §Errors covers when to use each
  hierarchy class.
- BUSINESS.md (278 → 225): collapsed prose to tables (use cases,
  competitive landscape, costs, risks); honest-status updated.
- DECISIONS.md (269 → 189): scoring rubric + GUI matrix preserved,
  decision log compressed to single-line entries, added v1.6 entries
  (Format Standardizer Ready, errors module).
- RECOVERY.md (180 → 147): rebuild steps as numbered + tabular,
  external dependencies as one table, recovery priorities tightened.

No information removed; redundancy compressed.
