feat(template-webpack-plugin): remove initialize compiler hooks

[luhc228]

1. compiler.hooks.initialize will not be called in child compilers, it is only called once in main compiler.

// the example of using `LynxTemplatePlugin` in child compiler
import { LynxTemplatePlugin } from '@lynx-js/template-webpack-plugin'

loaderContext._compilation.createChildCompiler(
  'child-compiler-name',
  {},
  [
     new LynxTemplatePlugin({ /* options */ })
  ]
)

2. Maybe it is not necessary to wrap in compiler.hooks.initialize.

📝 Walkthrough

Walkthrough

Move entryName-to-filename generation and output handling from compiler.hooks.initialize to the LynxTemplatePluginImpl constructor. The initialization hook is not invoked in child compilers, so this relocation ensures the logic executes during plugin construction.

Changes

Cohort / File(s)	Summary
Initialization Refactoring .changeset/thin-webs-enjoy.md, packages/webpack/template-webpack-plugin/src/LynxTemplatePlugin.ts	Moves entryName-to-filename generation and per-output handling from compiler.hooks.initialize to constructor; removes unused initialize hook due to lack of invocation in child compilers; maintains existing logic with updated timing.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~12 minutes

• Verify that moving logic from initialize hook to constructor doesn't affect initialization order or side effects
• Confirm the relocation works correctly in both parent and child compiler contexts
• Validate that per-output filename processing still executes as expected

Poem

A hook that never fires in the child's domain,
Now springs to life within the constructor's frame,
Filenames computed early, outputs arranged with care,
The initialization dance finds its proper lair! 🐰✨
