fix: check the frame QueryInterface result in dxgi capture

Both AcquireNextFrame paths cast the IDXGIResource to ID3D11Texture2D without looking at the HRESULT. ohgodwhat() then dereferences the null pointer in GetDesc(), and get_texture() hands a null texture to the vram encoder. Return the error instead. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011sw75MSAz7PTqrSALdStXe
fix: reuse the dxgi staging texture instead of one per frame

 * Accept a little duplication over a restructure. A new function that repeats a few lines of an existing one is a better diff than reshaping the original so both can share it.
 * Put new logic in self-contained functions in the module it belongs to (platform-specific logic in `src/platform/`, with `use` inside the function body to avoid churning shared import blocks). Call sites in shared files (`src/tray.rs`, `src/core_main.rs`, `src/server/connection.rs`, …) should be thin one-line hooks.

-### Scope check before touching shared code
-
-* Before changing a shared trait, a shared struct, or the signature of a widely used function, check whether the bug or feature is specific to one path. If it is, keep the change inside that path unless that is impossible, and say in the PR why it was.
-* If an unrelated caller needs `Default::default()`, `None`, or another placeholder solely to satisfy a signature you changed, the diff is too broad: stop and redesign.
-* The expected shape of a fix is a new function in the feature's own module, plus at most a new field or a thin hook in the shared code it needs. Feature-specific state belongs beside the feature's existing state, not in a new abstraction every caller has to learn.
-
-### Mandatory regression-surface check
-
-Before considering any implementation complete, perform a minimization pass over the final diff.
-
-* Inspect every modified existing file and every modified existing code path. Each must be strictly necessary for the requested change. Revert changes that are merely cleanup, refactoring, consistency improvements, or fixes for pre-existing issues.
-* For new features, preserve the existing implementation path when the feature is disabled or unsupported whenever practical. `feature off` should run the old code, not a rewritten equivalent.
-* Do not route existing behavior through a new abstraction merely to share code with the new feature. Prefer a parallel new function or a small amount of duplication over changing a proven existing path.
-* Keep new implementation logic in new or feature-specific modules. Changes to shared/core files should normally be thin hooks, capability checks, or protocol plumbing.
-* Do not fix unrelated pre-existing bugs in the same PR. Put them in a separate change unless they directly block correctness or security of the requested work.
-* For submodule bumps, inspect the exact commit range and ensure unrelated changes are not being pulled into the parent PR.
-* Before finalizing, explicitly report the regression surface: list the existing files and existing runtime paths whose behavior changed, and explain why each change is unavoidable.
-* During review, treat an unnecessarily modified legacy path as a review finding even if tests pass and the rewritten behavior appears equivalent.

-# webrtc-util: reads the Windows adapter list's IPv6 addresses as host-order u16 groups, so every
-# one comes out byte-swapped, fails to bind, and ICE gathers no IPv6 host candidate on Windows.
-# webrtc-sctp: RFC 4960's 1s RTO floor makes a single loss cost 1-3s on a link whose RTT is 24-64ms,
-# and fast retransmit cannot cover a request/response exchange; INITIAL_MTU 1228 also fragments on
-# IPv6; and its AIMD pins a lossy long-haul link to MSS/(RTT*sqrt(p)), so a switch sends without
-# a congestion window, as KCP does - on by default, `allow-webrtc-congestion-control` opts back in.
-# Sending that way, a reordering window keeps a chunk that is merely late from being resent on a
-# path that jitters, every DATA chunk asks for its SACK at once so a lost tail is back within an
-# RTT at KCP's RTO floors, and bundles of small chunks stay within the MTU. A T3-rtx resends
-# everything outstanding when it packs into four packets and otherwise probes with one and lets
-# the SACK settle the rest (F-RTO), timed from the latest send, so a stall no longer resends the
-# whole backlog behind itself while a short lost tail still comes back at once.
-# Pinned by rev, not branch: a fork branch can be rewritten out from under the lockfile.
