conductor+layout: remove T-shirt size metric, regenerate stale layout

Per user feedback 2026-06-17:
- T-shirt size is not an acceptable sizing metric. Remove it from
  conductor/workflow.md (the policy file), conductor/tracks.md (the
  registry), and docs/reports/NEGATIVE_FLOWS_INVESTIGATION_20260617.md.
- Regenerate manualslop_layout.ini to remove 83 stale window references
  that pointed to deleted/renamed windows (Projects, Files, Screenshots,
  Provider, System Prompts, Discussion History, Comms History, etc.).
  Layout now matches the windows registered in src/app_controller.py
  _default_windows (lines 1862-1886). Stale window count: 10 -> 3.

T-shirt size removal details:
- conductor/workflow.md: Removed the S/M/L/XL table, the replacement
  pattern row, and the 'reasonable effort' guard's reference. Scope
  (N files, M sites, N tasks) is the only effort dimension.
- conductor/tracks.md: Removed the T-shirt column from the table header
  and removed T-shirt size mentions from the Fable track entry.
- docs/reports/NEGATIVE_FLOWS_INVESTIGATION_20260617.md: Removed the
  T-shirt size mention in the follow-up track suggestion.

Layout fix:
- manualslop_layout.ini went from 17,360 bytes (102 windows, 83 stale)
  to 3,361 bytes (23 windows, all matching _default_windows). The
  stale window warning dropped from 10 windows to 3 (Message, Tool
  Calls, Response - these are in _default_windows but reference
  separate panels in the layout).

Verification: layout fix did NOT fix the underlying stack overflow crash.
After layout fix, the test still dies with rc=3221225725 (0xC00000FD).
The user noted 'Something more fundamental is wrong.' Investigation
continues; this commit only addresses the explicit ask (remove T-shirt,
fix layout).
