Reconcile Windows preview evidence after second wave

[coneilen]

Summary

Reconciles the Windows preview source of truth after the completed quick-start,
bootstrap, and redirected-profile queue. It preserves the strict parity ledger
while recording the remaining permission-bound #556 and #560 work.

Changes

• update the accepted main and merged PR/issue lineage through ca535d0c
• record the exact 3-open/10-closed assigned issue inventory and second-wave evidence limits
• replace the completed queue with a bottom-up Windows first-run onboarding blocks daemon connection; main window shows "Disconnected" and dialog has no UIA tree #556/UIA live gate times out (GetFirstChild 0x80131505) after overview-lane Worktrees click #560 orchestration and explicit Windows: split App.zig by responsibility to enable parallel preview and parity work #564/provider deferrals
• retain all 98 parity rows at 62 Validated and 36 Partial with an exact 36-row delivery mapping

Test plan

RED: pwsh -NoProfile -File C:\Users\coneilen.copilot\session-state\1e6781fe-3b8e-40e2-a7ef-25970805106c\files\Test-WindowsPreviewDocs.ps1 -RepositoryRoot D:\depot\copilot-worktrees\GraphCode\coneilen-microsoft-ideal-enigma -> 23 assertions failed on stale issue states, source provenance, inventory, and orchestration
GREEN: pwsh -NoProfile -File C:\Users\coneilen.copilot\session-state\1e6781fe-3b8e-40e2-a7ef-25970805106c\files\Test-WindowsPreviewDocs.ps1 -RepositoryRoot D:\depot\copilot-worktrees\GraphCode\coneilen-microsoft-ideal-enigma -> PASS with 98 rows, 62 Validated, 36 Partial, 36 exact mappings, 13 issues, and seven gates
REGRESSION: pwsh documentation contract plus live gh issue inventory plus git diff --check -> PASS with open #556/#560/#564, 10 closed assigned issues, exact accepted main, and clean diff

The failing and passing outputs are preserved separately in the session artifact
directory. An initial scratch-contract invocation hit a PowerShell interpolation
parser error; it was corrected before the retained 23-assertion RED and is not
used as documentation evidence.

make test and make check were not run because this PR changes only the two
investigation Markdown documents. The focused contract, live GitHub inventory
assertion, exact Partial-row mapping, seven-gate assertion, and
git diff --check passed.
