fix(components-scan): import files and apply exclude patterns on Windows

On Windows, @tsed/components-scan (glob patterns in imports, componentsScan and mount) had two problems.

1. importFiles couldn't import anything. globby returns absolute paths like C:/app/controllers/a.js. Passing those to import() fails in Node's ESM loader with ERR_UNSUPPORTED_ESM_URL_SCHEME ("Received protocol 'c:'"). Files are now imported through pathToFileURL(file).href. Vitest resolves the bare path itself, so the existing tests didn't catch this.

Reproduced with the published package (8.38.5) on Windows 11 / Node.js 24.14.0 in an ESM project:

import {importFiles} from "@tsed/components-scan";
await importFiles(["./controllers/*.js"], []);
// before: ERR_UNSUPPORTED_ESM_URL_SCHEME
// after:  [ [class Ctrl] ]

2. Exclude patterns were ignored. cleanGlobPatterns added ! and only then passed the pattern to normalizePath, which calls path.join. On Windows, path.join("!C:\app\a.ts") returns .\!C:\app\a.ts, so globby receives ./!C:/app/a.ts, which is not a negated pattern. As a result, "should import symbols without excluded files" fails on Windows on production. The path is now normalized first and negated afterwards. On POSIX the patterns come out the same as before.

Todos

• Tests: importFiles.spec.ts checks that files are imported through file URLs, and cleanGlobPatterns.spec.ts checks that an absolute exclude pattern stays negated. On Windows both new tests fail without the fix. yarn vitest run in the package passes 9/9 (before: 1 failing test on Windows).

Summary by CodeRabbit

• Bug Fixes
  • Improved component scanning with more reliable handling of excluded files and glob patterns, including absolute and Windows paths.
  • Fixed file imports for discovered files on Windows by converting paths into compatible file URLs.
  • Improved path normalization and extension handling for more consistent scan results across platforms.

Walkthrough

The components scan now normalizes absolute glob exclusions and converts discovered file paths to file URLs before dynamic imports. Tests cover both path handling changes.

Changes

Components scan path handling

Layer / File(s)	Summary
Glob path normalization packages/third-parties/components-scan/src/cleanGlobPatterns.ts, packages/third-parties/components-scan/src/cleanGlobPatterns.spec.ts	Glob paths are normalized and extension-mapped before negation. Tests cover absolute exclusions.
File URL imports packages/third-parties/components-scan/src/importFiles.ts, packages/third-parties/components-scan/src/importFiles.spec.ts	importFiles passes pathToFileURL(file).href to dynamic import(). Tests verify the conversion call.

Merge Risk: 🟡 Moderate · up to 428b6

Users relying on negated component-scan globs can have explicitly excluded files imported, so this should be corrected before merge.
