Fix DLSS artifacts and improve synchronization diagnostics

- Fix Cyberpunk 2077 preset-K black artifacts by preserving FP16/FP64
  denormal requirements while limiting denormal suppression to FP32.

- Fix stale direct-output redirects after array destruction, preventing
  reused handles from inheriting an earlier feature's output buffer.

- Log rejected resource formats and dimensions, including failures after
  startup, with rate limiting for repeated errors.

- Add opt-in blocking output synchronization with a dedicated bridge
  export and fallback to context synchronization.

- Report output-wait CPU and wall time, and defer GPU timing queries
  until asynchronous evaluation has completed. The CPU-overhead
  mitigation for #7 still needs reporter confirmation.

- Reject release libraries requiring GLIBC newer than the configured
  baseline, defaulting to 2.41, and document compatible builds.

Validation: shim and bridge builds pass; targeted redirect-lifetime and
format-logging checks pass.
