feat: implement V3 audit & enhancement — 8 parallel agents

Infrastructure: fix badge counts (251 projects, 35 concepts, 34 quizzes),
Python version matrix in CI (3.11/3.12/3.13), expand test coverage to ~24
projects, remove .DS_Store + 8 redundant shell scripts, fix social plugin deps

Navigation: fix all root doc chain failures (0 errors), consolidate 14 audit
files to _audits/, add practice tools discovery to START_HERE + GETTING_STARTED,
update README concept listing to all 35 docs

Content: 15 new quizzes (172 questions, 100% concept coverage), 8 module
flashcard decks (120 cards), 6 bridge exercises (levels 1-2 through 8-9)

Pedagogy: WHY-comments added to 109 project files across levels 4-10, elite
track, and modules. Levels 00-3 already had excellent coverage.

Accessibility: ARIA labels, roles, viewport fixes on 5 browser HTML files,
3 new browser exercise pages (levels 3-5) with full a11y compliance

Gamification: XP tracker, streak tracker, rich terminal dashboard, XP config
with 5 milestones, integrated into grade.py/quiz helpers/flashcard runner,
time estimates + checkpoint markers on 90 level 0-5 READMEs
