Add 21 missing SysAbi exports and GUI Environment tab for SHARPEMU_* toggles (#189)

Fills NID gaps hit by PS5 titles during boot, controller setup, and
rendering, and surfaces the common runtime switches in the GUI. All
exports are additive (no behavior change to existing exports) and free of
NID and export-name collisions with upstream.

New export libraries:
- libSceBluetoothHid: Init/RegisterDevice/RegisterCallback success stubs so
  titles proceed past Bluetooth controller setup (opt-out via
  SHARPEMU_BTHID_UNAVAILABLE=1).
- libSceNpCppWebApi: Common::initialize no-op success; UE5 online titles
  abort PS5-component startup on a negative SCE error.

Additions to existing libraries:
- libScePad: scePadOpenExt (shared PadOpenCore, accepts special ports 1/2 and
  the ScePadOpenExtParam pointer), scePadClose, scePadGetExtControllerInformation.
- libSceVideoOut: sceVideoOutConfigureOutput, sceVideoOutInitializeOutputOptions.
- libSceAgc: DCB builders sceAgcDcbSetIndexCount, sceAgcDcbJump, DcbSetPredication,
  SetPacketPredication (emit valid skippable packets; full draw processing TODO).
- libSceAmpr: measure and write KernelEventQueueOnCompletion pair.
- libKernel: scePthreadGet/Setschedparam, sceKernelChmod (validate and accept;
  POSIX permission bits have no host equivalent on Windows).
- libSceNetCtl: sceNetCtlRegisterCallbackV6 (delegates to the v4 callback).
- libSceMouse: sceMouseInit.
- libSceUserService: sceUserServiceGetAgeLevel (adult, skips parental gates).

GUI: new Options Environment tab exposing common SHARPEMU_* switches as
toggles (BTHID_UNAVAILABLE, DISABLE_IMPORT_LOOP_GUARD, VK_VALIDATION,
DUMP_SPIRV, LOG_DIRECT_MEMORY, LOG_NP). Persisted in gui-settings.json and
applied to the emulator process environment at launch; localized with
English fallback.

+# Contributing
+
+Contributions are always welcome!
+
+Before opening a pull request, please keep the following in mind:
+
+- Keep PRs small and focused on a single topic.
+- Discuss large architectural changes before implementing them.
+- Follow the project's existing coding style.
+- Do not submit generated code unless you fully understand and can maintain it.
+- Do not introduce Sony proprietary code, firmware, keys, decrypted assets, or other copyrighted PlayStation materials.
+- All reverse engineering should be based on publicly available information, clean-room techniques, or your own original research.
+- Game-specific hacks should be avoided whenever possible. Prefer generic implementations that improve overall compatibility.
+- New features should not break existing behavior.
+- Ensure the project builds successfully before submitting a PR.
+
+If you're unsure about a design decision, feel free to open a discussion or draft PR first.
+
+## AI-Assisted Contributions
+
+AI-assisted development is welcome and may be used for research, reverse engineering, code generation, or documentation.
+
+However, contributors are expected to fully understand every line of code they submit. By opening a pull request, you confirm that you are able to explain, modify, debug, and maintain the submitted code without relying on the AI that generated it.
+
+When submitting an AI-assisted PR:
+
+- Clearly explain **what the change does**, **why it is needed**, and **what problem it solves**, using your own words.
+- Describe **how you verified the change**, including the games, applications, or test cases used.
+- Avoid excessive product-level logging. Use logging only when it provides meaningful diagnostic value.
+- Comments should document design decisions or implementation details in your own words. Avoid generic AI-generated comments that merely restate what the code already does.
+- Be prepared to answer review questions about the implementation. "The AI generated it" is not considered a sufficient explanation.
+- Large AI-generated changes without a clear understanding of the implementation are unlikely to be accepted.
+- If the implementation cannot be reasonably explained during code review, the pull request may be rejected regardless of whether it works.
+
+The quality, correctness, maintainability, and long-term ownership of the submitted code remain the responsibility of the contributor.
+
+## Coding Style
+
+SharpEmu follows a consistent coding style across the project. Please ensure your contributions match the existing style.
+
+- Use **4 spaces** for indentation (no tabs).
+- Use **2 spaces** for XML-based files (e.g. `.csproj`, `.props`, `.targets`, `.xml`, `yml`, GitHub workflow files where applicable).
+- Respect the project's `.editorconfig`.
+- Ensure every text file ends with a **single trailing newline**
+- Avoid formatting-only commits unless they are the purpose of the PR.
+- Keep naming, formatting, and file organization consistent with the surrounding code.
+- Prefer small, focused changes over large refactors.
+
+### REUSE Compliance
+
+This repository follows the REUSE Specification.
+
+Every new file must contain the appropriate SPDX license header. Pull requests that do not comply with the project's REUSE requirements will fail CI and will not be merged.
+
+### Recommended Development Environment
+
+The repository includes an `.editorconfig` and Visual Studio solution files.
+
+For the best experience, we recommend using:
+
+- Visual Studio Code with;
+  - C#
+  - C# Dev Kit
+
+Most editors that support `.editorconfig` will automatically apply the project's formatting rules.
