v1.1.0: full CCAR-F track

Added

• Full CCAR-F (Claude Certified Architect – Foundations) track: overview, the six exam scenarios, five domain study
  guides, practical exercises, decision scenarios, misconceptions, revision notes, readiness assessment and exam-day
  guide, with an objective map and a generated coverage matrix (30/30 objectives)
• 131 CCAR-F practice questions, each tagged with one of the six exam scenarios (scenario_set), and three CCAR-F mock
  forms that mirror the exam's "4 of 6 scenarios" structure
• CCAR-F flashcard deck (133 cards)
• Independent answer-key review of the new CCAR-F bank: no wrong keys; two ambiguous items, one over-broad
  explanation and several near-duplicate or template-like items rewritten
• Six Domain 7 questions on Claude Code operations (.mcp.json scope, worktrees, hook matchers) for CCAO-F and CCAR-P
• Website: a card grid of starting points on the home page, and link-preview (Open Graph and Twitter) metadata using
  the social preview image

Changed

• Sonnet 5.5 cache-read price corrected to $0.10 per million tokens (labs 17 and 19, metrics and ROI examples)
• Data-residency guidance: inference_geo accepts only us and global; pinning another region uses a cloud
  platform's regional endpoint (question CCAR-P-D5-016 and three module pages)
• Answer-key review fixes to CCAR-P questions D2-006, D5-016, D7-001 and D7-003
• MCP cheat sheet uses MCPServer (MCP Python SDK v2); 16 Unverified notes re-checked: 13 confirmed or corrected, 3 still open
• tools/shuffle_options.py now requires --check, --ids or --all, so a stray argument cannot reshuffle every bank
• Getting-started pages, roadmaps, FAQ, exam facts and the social preview now cover three supported tracks
