Add auto-updater, Apple signing prep, and fix git status loop

[erictli]

Summary

• Auto-updates: Add tauri-plugin-updater with pubkey and GitHub release endpoint so the app can check for and install updates
• macOS release prep: Configure bundle targets (dmg, app), set minimum system version to 10.15, and gitignore .env.build secrets
• Fix git status infinite loop: refreshStatus in GitContext had status in its useCallback deps, creating a cycle where every status fetch triggered a re-render that re-fired the effect. Replaced with refs for initial-load tracking, in-flight protection, and a stable file-change listener

Test plan

• Verify app builds and launches with npm run tauri dev
• Confirm git status in footer updates correctly without blinking/flickering
• Type rapidly in a note with git enabled — footer should remain stable
• Verify updater plugin initializes without errors

📝 Walkthrough

Walkthrough

The PR integrates the Tauri updater plugin into the application by adding dependencies, initializing the plugin in the Tauri builder, and configuring updater settings. Additionally, it refactors GitContext to manage refresh state using internal refs, preventing concurrent operations and eliminating unnecessary re-renders.

Changes

Cohort / File(s)	Summary
Updater Plugin Integration .gitignore, package.json, src-tauri/Cargo.toml, src-tauri/capabilities/default.json, src-tauri/src/lib.rs, src-tauri/tauri.conf.json	Adds @tauri-apps/plugin-updater and tauri-plugin-updater dependencies, initializes the updater plugin in the Tauri builder, grants updater capability permissions, and configures updater settings including GitHub endpoints and public key. Also restricts macOS build targets to dmg and app, sets minimum macOS version to 10.15, and adds .env.build to gitignore.
State Management Refactoring src/context/GitContext.tsx	Introduces hasLoadedRef and refreshInFlightRef to manage load state and prevent concurrent refresh invocations without triggering re-renders. Adds stable refreshStatusRef to prevent re-registering file-change listeners. Updates dependency array and simplifies loading spinner logic to only display on first load.

Poem

🐰 A plugin arrives, the updater takes flight,
Refs manage the state, no re-renders in sight,
GitHub now beckons for fresh builds to share,
While debounce listeners float light as the air! 🚀
