feat: include python (w/ sphinx) support

[gbrasil720]

This pull request adds full support for Python Sphinx-style documentation comments to the extension, including syntax highlighting, completion, and parsing. The main changes introduce a new parser for Python docstrings, update configuration to recognize Sphinx patterns, and improve completion and detection logic for Python comments.

Python Sphinx Documentation Support

• Added full support for Python Sphinx-style comments in the documentation, including listing Python/Sphinx in the supported languages table and providing an example in README.md. [1] [2]

Configuration Updates

• Added Sphinx-specific patterns (:param, :returns, :raises) to the default comment patterns for highlighting and completion in src/config/default-patterns.config.ts.
• Updated language configuration to properly detect Python docstrings using regex, removed Python from hash-based comment detection, and set block comment lengths for Python docstrings in src/config/language.config.ts. [1] [2] [3]

Parser and Pattern Recognition

• Added PythonParser for extracting and parsing Sphinx-style docstrings, including handling parameters, return values, types, and exceptions in src/parsers/python.parser.ts and registered it in the parser factory. [1] [2] [3]
• Updated parser patterns configuration to include Python-specific comment detection, block extraction, code extraction, documentation parsing, and cleaning logic in src/config/parser-patterns.config.ts. [1] [2] [3] [4] [5]

Completion and Extension Logic

• Refactored completion provider to dynamically fetch patterns from configuration, detect if the cursor is inside a Python docstring, and provide Sphinx-style completions; streamlined activation logic in src/extension.ts and src/providers/comment-completion.provider.ts. [1] [2]

Pull Request Overview

This PR adds comprehensive Python Sphinx documentation support to the extension. It enables syntax highlighting, code completion, and parsing for Python docstrings using Sphinx/reStructuredText conventions like :param, :returns, and :raises tags.

Key changes:

• Added Python parser for extracting and parsing Sphinx-style docstrings
• Updated configuration to properly detect Python docstrings and exclude Python from hash-based comment detection
• Refactored completion provider to support dynamic pattern fetching and Python docstring detection

Duplicate parser instances are being created. Lines 12-14 create three CppParser instances and lines 16-17 create two JavaScriptParser instances. This array appears to be unused but creates unnecessary object instances.

Suggested change

	export const PARSERS = [
	new CSharpParser(),
	new CppParser(),
	new CppParser(),
	new CppParser(),
	new JavaParser(),
	new JavaScriptParser(),
	new JavaScriptParser(),
	new PHPParser(),
	new RustParser(),
	new PythonParser(),
	];

The completion logic is inconsistent. Line 11 uses the full pattern as the label, but line 12 removes the '@' prefix for insertion. This creates confusing completion items where the displayed text doesn't match what gets inserted.

Suggested change

	item.insertText = pattern.pattern.startsWith('@') ? pattern.pattern.substring(1) : pattern.pattern;
	item.insertText = pattern.pattern;

Empty configuration change handler serves no purpose. The previous implementation updated completion patterns when configuration changed, but this functionality has been removed without explanation.

I tested the extension with the proposed Python Sphinx documentation support, but I ran into several issues that prevent merging at this time:

• Autocomplete conflicts and bugs, The current implementation causes inconsistencies in code completion, especially around Python docstrings, which makes it unreliable for daily use.
• Copilot suggestions indicate unresolved issues, For example:

src/parsers/index.ts: Duplicate parser instances (CppParser and JavaScriptParser) create unnecessary objects.
src/providers/comment-completion.provider.ts: Completion logic is inconsistent; the displayed text sometimes differs from the inserted text, causing confusion.
src/extension.ts: The configuration change handler is empty, removing previous functionality without explanation.

Given these conflicts and bugs, I recommend holding off on this PR until the issues are resolved. Once these points are addressed, the extension can be safely merged with full Python Sphinx support.
