refactor: extract package.json scripts to .mjs files

Replace inline shell scripts with Node.js .mjs files for better customization, maintainability, and cross-platform compatibility.

New scripts:
- scripts/build.mjs: Build orchestration with --src-only, --types-only, --ink-only flags
- scripts/clean.mjs: Clean artifacts with granular --cache, --dist flags
- scripts/check.mjs: Run quality checks (lint fix, ESLint, TypeScript)
- scripts/lint-fix.mjs: Sequential linter execution with --dist, --external flags
- scripts/coverage.mjs: Coverage collection with --code-only, --type-only, --percent flags
- scripts/utils/: Shared command execution and utility functions

Benefits:
- Easier to add conditional logic and custom flags
- Better error handling with proper exit codes
- Cross-platform compatibility (no shell-specific syntax)
- Improved maintainability and testability

Updated lint-staged to call tools directly instead of through removed pnpm script aliases.

Integrated minify into build:pkg via MINIFY env var instead of separate script.

Pattern follows socket-sdk-js implementation and docs/SCRIPTS.md guide.
