Fix trailing whitespace in AGENTS.md causing pre-commit hook failures in PR #3

[Copilot]

PR #3 fails CI because the trim-trailing-whitespace pre-commit hook modifies AGENTS.md during validation, causing the build to fail with "files were modified by this hook."

Changes

• AGENTS.md: Removed trailing whitespace from lines 147, 149, 152, 155 in the Python docstring example

The issue occurs in blank lines within a code example that contained 4 spaces before the newline:

def algorithm_name(input_data, param=default):
    """
    Brief description of what the algorithm does.
    ⎵⎵⎵⎵  # 4 trailing spaces - causes hook to fail
    Time complexity: O(n log n)

Applied fix: sed 's/[[:space:]]*$//' to strip all trailing whitespace.

Application to PR #3

The maintainer can apply this fix to PR #3's copilot/setup-copilot-instructions branch via:

git fetch origin pull/3/head:fix-pr3 && git checkout fix-pr3
sed -i 's/[[:space:]]*$//' AGENTS.md
git commit -am "Fix trailing whitespace in AGENTS.md"
git push origin HEAD:copilot/setup-copilot-instructions

Or cherry-pick from this PR: git checkout origin/copilot/fix-failed-tests-on-pr -- AGENTS.md

The documentation states Ruff uses rules 'E,F,I,B,UP etc.' but according to pyproject.toml line 39, 'UP' is explicitly ignored. The comment should be updated to reflect the actual configuration: 'E,F,I,B' without mentioning UP as an active rule.

Suggested change

	# Lint code (Ruff rules E,F,I,B,UP etc.)

The documentation references fix-up utilities fix_leetcode_syntax_corruption.py and fix_comprehensive_leetcode_corruption.py, but these files do not exist in the repository. Only scripts/leetcode_manager.py is present. This section should be updated to reference the actual existing scripts or removed if these utilities were deprecated.

Suggested change

	- **Fix-up utilities:** `fix_leetcode_syntax_corruption.py`, `fix_comprehensive_leetcode_corruption.py`
	- These scripts enforce **consistency of the LeetCode-style notebooks**
	- **Do not modify them casually**—they maintain notebook formatting standards
	- Run these scripts after making changes to notebook files
	- **Notebook management utility:** `scripts/leetcode_manager.py`
	- This script enforces **consistency of the LeetCode-style notebooks**
	- **Do not modify it casually**—it maintains notebook formatting standards
