docs(deck): add 8 current-state slides + fix stale agenda

Brought warner-claude-code-may-2026.pptx current without touching the existing
boilerplate slides (all 48 original images preserved, 33 -> 41 slides).

Added 8 native slides after the framing (positions 10-17), matching the deck's
gray-banner style: Claude Code today (Sonnet 5 / 1M / 200K->1M scale bar), the
model lineup table, the Zero->Context->Agents->Hero arc, the CLAUDE.md scope
hierarchy, the agent loop with boundaries, MCP reach (.mcp.json / stdio +
Streamable HTTP / spec 2025-11-25), the Hero toolkit, and a resources slide.
Five diagrams rendered from Mermaid in the deck palette.

Fixed the one stale editable fact: slide 3 agenda now reads the current arc
(Context: CLAUDE.md / Agents: Loop & Subagents / Hero: Skills, Subagents, MCP).

Validated: renders via PowerPoint COM, opens clean, zip integrity OK, all model
IDs current with zero stale IDs.
