impr: replace vite-plugin-checker with ~~vibe~~ (@miodec)

[Miodec]

vite plugin checker seems to happily spawn a new linting process per file save, causing issues. This vibe coded solution kills the previously running process. It also splits linting into two steps to get some fast fail behavior.

I (AI) tried to merge it into one file but the overlay refused to show that way.

Pull request overview

This PR replaces vite-plugin-checker with a custom oxlint checker implementation to address issues with multiple concurrent linting processes being spawned on each file save. The custom solution includes process management that kills previous runs before starting new ones and implements a two-step linting approach (fast non-type-aware check followed by type-aware check) for faster failure feedback.

Key Changes:

• Removed vite-plugin-checker dependency and implemented custom oxlintChecker Vite plugin
• Added two-phase linting: fast baseline check followed by type-aware check for improved performance
• Implemented process management to kill previous linting processes when new changes are detected
