update_text_document performs redundant unquote and dict lookups

[meymchen]

Component

pygls/workspace/workspace.py

Summary

update_text_document calls unquote(doc_uri) and self._text_documents[...] twice in succession on every text change, which can be very frequent during normal editing.

Steps to Reproduce

1. Type a single character in a document.
2. didChange triggers two identical unquote and dictionary lookups.

Expected Behavior

Single lookup and unquote per edit.

Actual Behavior

Redundant operations on the hot path.

Affected Code (pygls/workspace/workspace.py, ~L280-282)

self._text_documents[unquote(doc_uri)].apply_change(change)
self._text_documents[unquote(doc_uri)].version = text_doc.version

Proposed Fix

doc = self._text_documents[unquote(doc_uri)]
doc.apply_change(change)
doc.version = text_doc.version
