docs: complete factual audit pass 2 — 90+ corrections

Second 10-agent parallel audit covering all remaining sections:
ultimate-guide.md (ch1-ch11), workflows/ (17 files), quiz/ (12 files),
examples/agents+skills+commands. Source of truth: official Anthropic docs.

Key corrections:

Hook system (+8 missing events):
- Complete 17-event list: PermissionRequest, PostToolUseFailure, SubagentStart,
  TeammateIdle, TaskCompleted, WorktreeCreate, WorktreeRemove, SessionEnd
- SessionStart confirmed valid (previous audit wrongly doubted it)
- Hook output format: hookSpecificOutput.permissionDecision (not {"decision":"block"})
- Missing common input fields added: transcript_path, cwd, permission_mode

Agent YAML frontmatter (13 valid fields restored/added):
- Restored: disallowedTools, memory, background, isolation, skills, permissionMode, hooks
- Added new: maxTurns, mcpServers
- Fixed: tools format is comma-separated (not space-separated)

Plan Mode (12 occurrences fixed):
- Ctrl+G = "open plan in text editor" (NOT "enter plan mode")
- Plan Mode = Shift+Tab × 2 (Normal → acceptEdits → plan)

Commands table (10.1) + built-in commands (6.1):
- Added 18+ missing commands: /copy, /doctor, /hooks, /memory, /model,
  /config, /permissions, /remote-control, /rename, /resume, /sandbox, etc.

Workflow files:
- agent-teams.md: removed fake --experimental-agent-teams flag
- hooks.yaml + post_edit event → settings.json + PostToolUse (2 files)
- TodoWrite → TaskCreate/TaskUpdate (3 files)
- task-management.md: removed fake "failed" task status

Quiz / examples:
- 01-010: Esc stops mid-action (not Ctrl+C)
- refactoring-specialist.md: removed MultiEdit (not a valid tool)
- ast-grep-patterns.md: name field (not title)
- validate-changes.md, diagnose.md: field name fixes
