feat: switched to native text sanitization, removed Bun.stripANSI

- Added `sanitizeText` function to pi-natives that strips ANSI escape sequences, removes control characters and lone surrogates, and normalizes line endings.
- Moved `sanitizeText` function from `@oh-my-pi/pi-utils` to `@oh-my-pi/pi-natives` for better code organization and native performance.
- Added line length clamping (4000 characters) to bash and Python execution output to prevent excessively long lines.
- Replaced internal `#normalizeOutput` methods with `sanitizeText` utility function in bash and Python execution components.
- Fixed bash interactive tool to gracefully handle malformed output chunks by normalizing them with `sanitizeText`.
- Simplified documentation by removing WASM terminology from package descriptions and comments.
