Please fill in the LLM disclosure; without it, I will just close the PR.

Remove all the superfluous doctree files. Only commit files that you edited.

try/except looks ugly in docs and is not useful for human readers.

Rather than forcing the test to pass, find a way to ignore it or use an existing trajectory.

Make it work as MDAnalysis.fetch.from_pdb(...) to maintain the fetch.from_XXX semantics.

…DB to from_pdb

- Remove all .doctree cache files from git tracking
- Add .gitignore for doctree cache and test artifacts
- Replace try/except in DCDFile, TRRFile, XTCFile docstrings with .. code-block::
- Rename from_PDB to from_pdb to maintain fetch.from_XXX naming convention
- Update tests and __init__.py for renamed function

You did not update the LLM disclosure, you made some changes that look like automatic changes to the code base that having nothing to do with the original issue, and you're not really engaging with me as a reviewer. I will therefore close this PR as likely pure AI-generated.

Please feel free to re-open a new PR and read our AI Policy first.
