Component release notes for dotnetmaui.md in .NET 11 Preview 7.

Targets the milestone base branch release-notes/11.0-preview7 (see #10501).

This content is AI-authored and needs a review pass from the component team before it goes ready-for-review.

Adversarial review found two documentation precision gaps:

• ⚠️ The passkey section omits mandatory platform trust configuration even though IsSupported only checks the OS version.
• ⚠️ The FastDeploy2 operation count is stated universally, but the cited implementation scopes three serial adb operations to the healthy warm incremental path.

Methodology: 3 independent reviewers with adversarial consensus; both findings reached 2/3 consensus after dispute.

Test coverage: Documentation-only change; no test code is expected. Factual claims were cross-checked against the linked implementation and setup documentation.

Prior review status: No existing reviews, issue comments, or inline threads were present.

Focused multi-round review of the delta from e56e3623 to 8fcb17e found four documentation issues:

• ⚠️ The XAML Hot Reload link does not document Incremental Hot Reload supported edits or limitations.
• ⚠️ The revised x:Reference fallback description names the wrong trigger; an unresolved reference name is a compile error.
• 💡 The TabbedPage article contains general usage guidance, not renderer-to-handler migration guidance.
• 💡 The media picker, window, and lifecycle pages do not yet cover the adjacent Preview 7 APIs, so calling them “updated” overpromises their content.

Methodology: 3 independent reviewers with adversarial consensus. The x:Reference and “updated documentation” findings reached 3/3 after dispute; the Hot Reload and TabbedPage findings reached 2/3. A disputed AncestorType finding was discarded after shipped source and a source-generator probe confirmed the current compile-failure statement.

The prior Passkeys trust-configuration and FastDeploy2 warm-path findings remain fully resolved and were not reopened.

Test coverage: Documentation-only delta. All new URLs resolve with the net-maui-11.0 moniker; linked content and shipped Preview 7 binding behavior were inspected directly.

Prior review status: The two earlier inline threads have author replies identifying their resolved fix commit; these comments do not duplicate them.
