feat(valleywide): drive 3 deep dive - VWP1.VHDX mount + 97-Server\VWP2 grab

Drive 3 yielded the biggest finds in the project so far.

VHDX mount + scan (D:\WIN7-Orders\Darv-2\VWP1.VHDX, 117 GB Hyper-V disk):
- Mounted read-only as F:, scanned in 85s, dismounted
- NOT Darv's dev box - it's the office "owner" admin workstation
- No newer source code found inside, but:
  - Vwp11.mdb (2023-07-27, 369 MB) - NEWEST DB snapshot anywhere
  - Vwp.mdb (2022-12-23, 769 MB) - on Desktop\Darv VWP
  - Orders Versions/ desktop folder with 2 EXEs + 7 shortcuts
  - The .lnk shortcuts all pointed to G:\VWP2\Orders*.exe - the
    "Aha!" that revealed where Darv's iteration happened
- Saved to source-code/from-VHDX-VWP1/

The VWP2 grab (D:\97-Server-G-Drive\g$ 2024-04-10\VWP2\):
- This is Darv's actual iteration workspace on the production
  Orders server (G: drive)
- 16.36 GB total, 1,061 files. Grabbed 886 files (~893 MB) filtered to
  *.exe, *.rpt, *.ocx, and VB6 source extensions:
  - 64 Orders*.exe versions - complete iteration history (includes the
    production Orders_10A.exe + Orders_10Z.exe variant + dozens more
    with Darv's "iterate-and-rename" naming pattern)
  - 820 Crystal Reports (.rpt)
  - 2 .ocx supporting controls
- Skipped 23 historical .mdb backups (15.8 GB) - we already have
  newer snapshots from 000_ASource and VHDX
- Skipped 6 large subfolders (HOLD, HHOLD, Pay_2021_0325, GWAC,
  20220205, 20211010 RPT) - mostly more MDBs
- Saved to source-code/from-VWP2-97server/

What we learned about the 4-year gap:
- No source code newer than 2020-06-09 ORDERS_C.vbp baseline found
  on any of the three rotation drives
- The 64 EXE versions in VWP2 go through 2022 - Darv was iterating
  and rebuilding compiled output but not updating his .vbp source
  control. This is consistent with his "rename and try" workflow
- The production exe (Orders_10A.exe) is in this batch - now we can
  use VB Decompiler Pro on it without needing the original drive

Helper scripts:
- scan_vhdx.ps1 - fast PowerShell scan of a mounted VHDX for source/DB
- find_vwp2.py - cross-CSV search for the VWP2 path
- vwp2_summary.py - size+type breakdown of the VWP2 folder
- debug_vwp2.py - one-off debug helper

 - **`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.
