fix: regenerate Windows ICO with all standard sizes (16-256px)

[Dexploarer]

Summary

The Windows icon (appIcon.ico) only contained 16x16 and 32x32 sizes. Windows needs 48x48, 64x64, 128x128, and 256x256 for proper display in the taskbar, desktop shortcuts, Start Menu, and Explorer.

Regenerated from the existing 512x512 source PNG (appIcon.png) with all 6 standard sizes.

Before: 15KB, 2 sizes (16, 32)
After: 370KB, 6 sizes (16, 32, 48, 64, 128, 256)

This is a binary ICO file replacement — no code changes, pure asset swap.

1. Classification: Aesthetic
2. Scope verdict: Out of scope
3. Code quality: N/A (binary asset only)
4. Security: Clear — binary diff is a single ICO file, no executable payload risk
5. Tests: N/A
6. Decision: CLOSE

Reason: This PR replaces a Windows ICO file with a regenerated version containing additional icon sizes (16-256px). Per the review protocol, frontend/visual asset changes that don't improve agent capability are explicitly out of scope. Icon quality improvements are aesthetic changes — they affect the human visual experience, not agent functionality, correctness, or reliability. Closing per policy.

Review: PR #1353 — fix: regenerate Windows ICO with all standard sizes (16-256px)

1. Classification: Aesthetic
2. Scope verdict: Out of scope
3. Code quality: N/A — binary asset only, no code changed
4. Security: Clear — binary diff of an ICO file poses no security concern
5. Tests: N/A
6. Decision: CLOSE

This is a binary ICO asset replacement with no functional impact on agent behavior, runtime correctness, or capability. The Milady project explicitly excludes "Frontend redesigns, aesthetic changes, theme changes, icon swaps" and "changes that prioritize human visual experience over agent quality." Adding more size variants to a Windows taskbar icon is purely a visual/aesthetic improvement for human users and does not belong in this codebase.

Closing per scope policy. Thanks for the contribution, Dexploarer — please focus future PRs on agent capability, bug fixes, or test coverage.
