refactor(astro): Replaced generic Error throws with AstroError

[jp-knj]

Changes

• remove todo comments
• Replaced generic Error throws with AstroError in packages/astro/src/content/loader/file.ts.
  • Adds contextual error names and messages:
    • Glob Pattern Error for disallowing * in file() loader paths.
    • Parser Not Found when no parser is available for the file extension.
  • Imports AstroError from core/errors so all runtime errors funnel through our unified error-handling layer.
• Changeset included (pnpm exec changeset) to surface in release notes.

Testing

• Ran the full test suite: pnpm test – all existing tests pass.
• Manual sanity check:
  1. Created a sample project with a bad data/*.json glob; verified the new Glob Pattern Error message surfaces in the terminal with the Astro error banner.
  2. Pointed the loader to an .xml file; saw the Parser Not Found message and helpful suggestion.

No additional tests added because logic remains identical; only the error-reporting wrapper changed.

Docs

No user-facing API changes. Docs remain valid.

Hi @jp-knj thanks for the PR! We follow a pattern for errors that is putting them in https://github.com/withastro/astro/blob/main/packages/astro/src/core/errors/errors-data.ts. Would you mind opening another PR for this?
