docs(agents): close W4 Windows shell wave

[blakinio]

Purpose

Close OTERYN-W4-WINDOWS-SHELL durably after its plan, implementation and both lifecycle archives merged.

Completed W4

Work	Delivery/archive
plan	#77 / #78
Windows application shell	#79 / #80

Current required main: ab0ac39ca70ccea6d8f7517f4119395de6b17017. All implementation Cargo/lockfile/dependency-policy/shared-document leases are released.

Delivered routing

• CURRENT_PARALLEL_WAVE.md is a completed/closed W4 record;
• COORDINATOR_AGENT.md authorizes planning only and cannot relaunch W1-W4;
• docs/agents/README.md requires a separate accepted plan before another worker/task/dependency/lease;
• MODULE_CATALOG.md records feat(rust): add Windows application shell #79/docs(task): archive Windows application shell #80 as merged/archived;
• unrelated open PRs feat(ui): prototype Oteryn login shell #23/fix(assets): select release archives by client version #37 remain legacy-only and ci: prove official Tibia login without OCR on Synology #48 remains isolated operational work.

Exactly one next recommendation

A bounded renderer surface-ownership evidence/spike consuming the merged application shell. This PR creates no task, branch, dependency change, lease or implementation for it.

Compatibility boundary

Interactive Windows launch/input/DPI/IME/minimum-release and all GPU/driver/hardware/performance behavior remain unproven and explicitly blocked for compatibility claims.

Scope

Exactly five coordination/catalogue documentation paths. No Rust source, Cargo, lockfile, dependency policy, CI, architecture, renderer, protocol, assets, legacy runtime or external-repository changes.

Validation

Exact final head: 43ce954d3f7f9a8f62209c48491d593f116447fe.

• live W4/archive/open-PR/lease preflight passed;
• complete five-file path/content review passed;
• exact-head required CI pending.
