Phase 3+4 rename reorg: repo dir renames + startnet.cmd menu

Pairs with Phase 1+2 from earlier (alias maps in Install-FromManifest,
GE-Enforce, Get-PCProfile, verify-state). See project-shopfloor-rename-reorg
memory for the plan.

Phase 3 (repo + paths):
- git mv per-PC-type dirs to gea-shopfloor-* names:
    Standard      -> gea-shopfloor-collections
    CMM           -> gea-shopfloor-cmm
    Keyence       -> gea-shopfloor-keyence
    Genspect      -> gea-shopfloor-genspect
    WaxAndTrace   -> gea-shopfloor-waxtrace
    Display       -> gea-shopfloor-display
    Lab           -> gea-shopfloor-common (folded; Timeclock+Lab merge)
- New gea-shopfloor-nocollections/ (clone of collections sans UDC scripts).
- New gea-shopfloor-heattreat/ (placeholder, README only).
- Move Standard/ntlars-backups/ -> _ntlars-backups/ (per-MN, not per-type).
- Run-ShopfloorSetup.ps1: Resolve-PCTypeDir helper walks alias group when
  the on-disk dir for the current pcType is missing. Set-MachineNumber
  helper-copy gated on collections|nocollections|legacy Standard-Machine.
- Update-MachineNumber.ps1: pcProfiles lookups try gea-shopfloor-collections
  first, fall back to legacy Standard-Machine. PowerShell 5.1 compatible
  (no null-coalesce).

Phase 4 (startnet.cmd menu):
- Choice 3 "GEA Shopfloor" now drills into a 9-item sub-menu instead of
  going straight to enrollment. Sub-cats:
    1. Machine with Collections        -> gea-shopfloor-collections
    2. Machine without Collections     -> gea-shopfloor-nocollections
    3. Common (Timeclock, Lab)         -> gea-shopfloor-common
    4. Keyence                         -> gea-shopfloor-keyence
    5. CMM                             -> gea-shopfloor-cmm
    6. Genspect                        -> gea-shopfloor-genspect
    7. Heattreat                       -> gea-shopfloor-heattreat
    8. Wax and Trace                   -> gea-shopfloor-waxtrace
    9. Display                         -> gea-shopfloor-display
- Office menu (existing 6-option) follows for every sub-cat.
- Machine number prompt only for collections + nocollections.
- pc-subtype.txt + display-type.txt no longer written. PCTYPE is a
  single full string (gea-shopfloor-*); subtype-aware code paths fall
  back to empty and resolve via the alias map.
- CMM bootstrap stage gate switched from "%PCTYPE%"=="CMM" to
  "%PCTYPE%"=="gea-shopfloor-cmm".

Test harness:
- B-enforce/run.sh PCSUBTYPE default changed from "Machine" to "" so
  single-arg invocation matches the new single-string scheme. Two-arg
  legacy form ("Standard Machine") still works via aliasing.
- B-enforce/tamper.ps1 alias-aware Test-MatrixEntryMatches mirroring
  verify-state.ps1.

Smoke-tested on win11 VM as SYSTEM via qga: B-enforce harness 5-phase
cycle (stage / baseline / tamper / heal / idempotent) passes 10/10
with PCType=gea-shopfloor-collections AND with legacy "Standard Machine"
two-arg form.
