chore: include AI model config (LLM/STT) in support chat context

[devin-ai-integration]

Summary

When users create issues via the in-app chat support, the GitHub issues now include the user's configured AI models (LLM provider/model and STT provider/model) alongside the existing device and account info. This helps with triaging — knowing whether a user is on a local STT model vs cloud, or which LLM provider they use, is useful context for debugging.

Changes:

• Added ModelInfo struct to template-support crate (LLM/STT provider + model, all optional)
• Extended SupportContext and the support_context.md.jinja template to render model info
• useSupportMCP hook now reads model config from TinyBase settings and passes it into the context collector
• Updated the support chat system prompt to instruct the LLM to include model info in filed issues
• Manually updated plugins/template/js/bindings.gen.ts (codegen could not run due to missing apple-contact/Cargo.toml in workspace)
• Fixed pre-existing formatting issue in plugins/tray/src/ext.rs (indentation + extra blank line) to pass fmt CI check

Review & Testing Checklist for Human

• Verify the manually edited bindings.gen.ts matches what specta codegen would produce. Codegen couldn't run (apple-contact plugin missing Cargo.toml). Run pnpm -F @hypr/plugin-template codegen once the workspace issue is fixed and confirm the ModelInfo type and SupportContext update match.
• Check the Jinja template indentation in support_context.md.jinja — the endif/if tags have inconsistent indent levels (some at 2 spaces, some at 4) which may produce unexpected whitespace in the rendered markdown context block.
• Test end-to-end: Open the support chat in the desktop app with LLM and STT models configured, file a bug report, and verify the created GitHub issue body includes an "AI Models" section with the correct LLM/STT provider and model values.

Notes

• The models field on SupportContext is optional (#[serde(default)]), so this is fully backward-compatible — existing clients without model info will just omit the section.
• useConfigValues for the model keys returns undefined when not set; the code converts to null via ??.
• Two non-required CI checks (check and check (macos-latest)) fail due to pre-existing clippy lints in shortcut-macos and cli crates, unrelated to this PR. All relevant checks (fmt, ci, check (ubuntu-latest)) pass.
