Outstanding flake8 findings (manual fix required)

flake8 reported 1,172 findings across analyzer/ and querygrade/. These require manual attention and are not addressed by this PR. Common categories:

• E501 — lines exceeding 88 characters (majority of findings)
• F401 — unused imports
• F841 — local variables assigned but never used
• E402 — module-level imports not at top of file
• W291/W293 — trailing whitespace (in comments/strings black doesn't touch)
