feat: add author-presentation template with presentation-kit format

[Alan-Jowett]

Summary

Add a new interactive template for authoring professional technical presentations from LLM session context. Produces a complete presentation kit: PowerPoint slides (via python-pptx), speaker notes, timeline, optional PDF export, and optional demo plan.

New Components

Type	Name	Path	Description
Protocol (reasoning)	presentation-design	protocols/reasoning/presentation-design.md	6-phase reasoning protocol: audience analysis, narrative arc, slide decomposition, visual design, time budgeting, demo choreography
Format	presentation-kit	ormats/presentation-kit.md	Multi-artifact output format for presentations: PPTX generation rules, theme presets, speaker notes, timeline, demo plan
Template	uthor-presentation	emplates/author-presentation.md	7-phase interactive template with adversarial plan review before content generation

Design Decisions

• Configurable persona: The domain varies by presentation topic (a security talk uses security-auditor, an architecture talk uses software-architect), so the persona is a parameter rather than fixed.
• No new persona needed: Presentation-specific reasoning (narrative arc, visual design, pacing) lives in the presentation-design protocol instead of a persona, keeping concerns separated.
• No taxonomy needed: Presentations don't produce classified findings, so no taxonomy was added.
• Adversarial plan review (Phase 3): A dedicated phase stress-tests the slide plan before content generation — checking audience-goal alignment, narrative coherence, evidence grounding, pacing, and failure modes.
• Python-pptx code generation: The template instructs the LLM to write and execute Python code to produce the actual .pptx file, similar to how ind-and-fix-bugs instructs the LLM to apply code fixes.
• Theme presets: Five built-in visual themes (Dark Tech, Light Clean, Warm Minimal, Corporate Blue, High Contrast) plus custom option, with sensible defaults.

Checklist

• All files have SPDX license headers
• YAML frontmatter is valid and complete
• Component names match file names (kebab-case)
• manifest.yaml updated with all new components
• No vague instructions in protocols or templates
• Protocol has numbered, ordered phases (6 phases)
• Template has a quality checklist section
• New components do not conflict with existing ones
• CI validation passes (python tests/validate-manifest.py → OK)

Pull request overview

Adds a new “presentation kit” document intended to let any presenter deliver the PromptKit Deep Dive deck confidently (speaker notes, demo script, FAQ, and timing guidance), aligning with PromptKit’s broader goal of making library usage and workflows easy to adopt and explain.

Changes:

• Added a slide-by-slide presenter script for the 19-slide Deep Dive deck.
• Added a 10-minute demo script (CLI quick start + Sonde case study beats).
• Added an FAQ, pre-talk setup checklist, and a slide timing/compression guide.
