feat(valleywide): add drive 2 findings - 000_ASource + analyzer outputs

Drive 2 (label "Backup", 12 TB, 6.77 TB used) — second of N VWP
backup drives. Scanned via WizTree, analyzed with analyze_wiztree.py.

NEW source content:
- 000_ASource/ — Darv's active work-in-progress folder. Contains
  TEST_VWP.vbp (2021-08-16, only .vbp newer than the 2020-06-09 baseline),
  four frmLotInfo*.frm variants (2020-10 to 2021-08), and an
  MSSCCPRJ.SCC file confirming Darv used Visual SourceSafe.
- The accompanying Vwp.mdb (2022-10-19, 764 MB) stays on local disk
  per .gitignore — newest database snapshot we have.

Analysis CSVs:
- source-analysis/drive2-2026-05-16/ — per-category + per-keyword
  breakdown of drive 2's 3.95M files (vs drive 1's 1.87M). Categories
  largely match drive 1 but with ~2x volume.

Net findings vs drive 1:
- Confirmed 4-year gap: only 4 .vbp files newer than 2020-06-09 on
  drive 2, all the same TEST_VWP.vbp scaffold. Main ORDERS_C.vbp source
  remains 2020-06-09. Darv stopped active VB6 dev around mid-2020.
- 43 GB Win7 Backup-and-Restore set in D:\Archive\Darv-Win7-PC\ (2023)
  not copied — deferred to later drives, ZIPs extractable on demand.
- Master Darv folder is bit-for-bit duplicate of drive 1's master (135 GB,
  same file/folder counts). Skipped.

New helper scripts:
- find_newer_vbp.py — list .vbp files newer than a date, filter SDK noise
- drive2_inspect.py / drive2_priorities.py — drive-specific triage

+### `000_ASource/` — Darv's "active source" folder (from drive 2)
+- **Source:** `D:\Office-Estimates\Darv\000_ASource\` (drive 2, label `Backup`, 12 TB)
+- 12 files, ~768 MB (mostly the `Vwp.mdb` which is gitignored — only ~4 MB of source/config goes to git)
+- **`TEST_VWP.vbp` dated 2021-08-16** — the only .vbp on either drive newer than the 2020-06-09 ORDERS_C.vbp baseline. Likely an experimental scaffold (only 810 bytes).
+- **`frmLotInfo*.frm` variants** dated 2020-10 to 2021-08 — Darv was iterating on a form. The `JJ` and `Z` and `5JJ` and `5Z` suffixes are his variant-marker convention.
+- **`Vwp.mdb` dated 2022-10-19** (764 MB) — newest database snapshot anywhere, two years more recent than what the prior session had. Gitignored; on local disk only. Useful for schema-evolution analysis.
+- **`MSSCCPRJ.SCC` file** — Microsoft Source Code Control project file. Confirms Darv was using **Visual SourceSafe**. There may be a SourceSafe repository (`srcsafe.ini`) on a later drive that contains full version history. Worth grepping for `*.scc / srcsafe.ini` on subsequent scans.
