chore: migrate koa-override into monorepo

[wangxpych]

Summary

• add the scoped @eggjs/koa-override package to the Egg monorepo
• preserve body and header method-override behavior, including empty-body fallback
• switch the Egg overrideMethod middleware to the workspace package
• add TypeScript declarations, Vitest coverage, build configuration, and wiki documentation

Closes #5798

Validation

• 7 targeted Vitest tests pass
• package TypeScript check passes
• targeted oxlint and oxfmt checks pass
• package build passes
• git diff --check passes

Summary by CodeRabbit

• New Features

  • Added Koa method-override middleware supporting _method request body fields and the X-HTTP-Method-Override header.
  • Supports configurable request methods eligible for overrides; POST remains the default.
  • Validates override methods and returns a clear error for unsupported values.
  • Integrated the middleware into Egg’s default middleware stack.

• Documentation

  • Added usage guidance, API documentation, licensing information, and package reference documentation.

Inline comments:
In `@wiki/packages/koa-override.md`:
- Around line 15-18: Update the description of the default restriction in the
koa-override documentation to state that method overrides are only processed for
POST requests by default, while non-POST requests pass through unchanged.
- Around line 5-8: Update the source_files metadata in the koa-override wiki
entry to include the test, build/type, and Vitest configuration paths plus
packages/egg/package.json supporting the claims around declarations, runtime
requirements, tests, releases, and workspace consumption; if evidence remains
unavailable, mark those claims as Inference: and record them as unresolved.
