fix(lint): transform filename from linter context to the absolute one for prefer-import-alias rule

[NriotHrreion]

Overview

context.filename provided by the linter is not guaranteed to be absolute, but prefer-import-alias just directly uses the context.filename to resolve the import paths, which causes unintended lint error in editor.

For example, in packages/vinext/src/server/api-handler.ts

import "./server-globals.js";
// Use alias 'vinext/internal/server/server-globals' instead of relative path './server-globals.js'. oxc(vinext-local(prefer-import-alias))

What changed

I added a function getPhysicalFilename(context) to get absolute filename from the linter context. This function resolves context.physicalFilename (if there is not, fallback to context.filename) to absolute with cwd.

And this function is called during createOnce():

+ const filename = getPhysicalFilename(context);
+ if (!filename) return;
- const aliases = loadAliasesForFile(context.filename);
+ const aliases = loadAliasesForFile(filename);
if (aliases.length === 0) return;
- const importerDir = path.dirname(context.filename);
+ const importerDir = path.dirname(filename);
