style(codegen, formatter, linter, minifier, transformer): re-order imports (#12725)

This PR addresses the import ordering violations identified in #12723 by
fixing import ordering across key files in the codebase to follow the
updated Oxc convention.

## Import Ordering Convention

The correct order is:
1. `std` imports
2. External crates
3. Oxc crates (starting with `oxc_`)
4. Local crate (`crate`)
5. `super`
6. `mod`

With line breaks between each category.

## Key Principle: Source Priority

Imports should be imported from the closest available source:
- Prefer to `use` from a local `mod` over `super` or `crate`
- Prefer to `use` from `super` over `crate`

This ensures we don't lose information about module structure and
maintain the most direct import paths.

## Changes Made

Fixed import ordering violations in 11 files based on comprehensive code
review feedback, ensuring all rules from #12723 are properly applied:

### Core Applications
- `apps/oxlint/src/lib.rs` - Fixed pub use positioning and
mod-before-use rule compliance
- `apps/oxlint/src/tester.rs` - Added required line break after imports

### Core Crates  
- `crates/oxc_language_server/src/main.rs` - Moved mod statements before
related use statements
- `crates/oxc_transformer/src/options/es_features.rs` - Added required
line break after imports
- Additional fixes in codegen, formatter, linter, and minifier crates

## Repository-Wide Analysis

Comprehensive analysis revealed 890+ additional files with import
ordering violations. However, automated fixing proved challenging due
to:
- Complex multi-line `use` statements with braces
- Relative imports within crate modules requiring careful handling
- Risk of breaking builds with overly aggressive automation

## Verification

- All changes maintain proper `rustfmt` compatibility
- Comprehensive build verification confirms all packages compile
successfully
- Source priority preserved - local module imports maintained over crate
imports where appropriate
- All tests pass with the updated import ordering

This represents the first phase of addressing #12723, with remaining
violations requiring careful manual review or enhanced tooling.
