Windsurf + Aider targets, MCP server, and demo placement (#33)

Broadens both reach (more tools) and content types (an MCP server), continuing
the multi-platform story.

Windsurf + Aider:
- build-exports.mjs gains two platforms: exports/windsurf/*.md (workspace rules,
  trigger: model_decision) and exports/aider/*.md (conventions for `aider --read`).
  Now 5 platforms (ChatGPT, Gemini, Cursor, Windsurf, Aider).
- install.sh + bin/cli.mjs install both (windsurf -> .windsurf/rules, aider ->
  .aider/skills with a --read hint); generated README index is excluded from copies.
- One-line windsurf-install.sh / aider-install.sh wrappers for parity.

MCP server (new content type):
- mcp/server.mjs — zero-dependency stdio MCP server exposing list_skills,
  search_skills, get_skill. Published as a second bin (pm-claude-skills-mcp).
  Logs to stderr; reads bundled skills/ at startup. mcp/README.md documents
  client config.

Also: README hero "See it in action" demo placement (ready to swap in a GIF;
recording guide in web/docs-assets/README.md), Works-With table + exports +
install docs updated, CHANGELOG Unreleased. package.json files/bin updated.

+# Patient Communication Skill
+
+Writes patient-facing healthcare communications in plain, accessible language — targeting UK Grade 6 / US Grade 8 reading level.
+
+WARNING: All patient communications must be reviewed and approved by a qualified healthcare professional before sending. This skill produces drafts only.
+
+## Required Inputs
+- **Communication type** (appointment letter / results letter / discharge info / patient leaflet / consent info / health education)
+- **Clinical context**
+- **Key messages** (what the patient must understand and do)
+- **Tone** (reassuring / informative / urgent)
+- **Specific instructions or next steps**
+- **Contact details for queries**
+
+## Output Structure
+
+### Type A: Patient Letter
+
+[Date]
+
+Dear [Patient name],
+
+**Re: [Clear subject line in bold]**
+
+[Opening paragraph: State clearly what this letter is about. No preamble.]
+
+[Main content — short paragraphs, 2-3 sentences each. Bullet points for instructions. Bold anything the patient must do or remember.]
+
+**What happens next:**
+- [Action 1 — specific with timeframe]
+- [Action 2]
+
+**If you have questions:**
+Contact us at [phone] between [hours] or email [address].
+
+If you feel unwell before your appointment, please [specific instruction].
+
+Yours sincerely, [Name, Title, Department]
+
+---
+
+### Type B: Patient Information Leaflet
+
+**[Plain language title]**
+
+**What is [topic]?** [2-3 plain English sentences. Explain technical terms immediately.]
+
+**Why has this been recommended for me?** [Personalised clinical reason in patient terms]
+
+**What will happen?** [Numbered step by step]
+
+**What are the benefits?** [Honest statement]
+
+**What are the risks?** [Common first, then rare but serious. Use frequencies: "About 1 in 10 people..." not "10% incidence"]
+
+**What should I do to prepare?** [Specific instructions]
+
+**When should I contact someone?** [Specific signs — not vague. "Temperature above 38C" not "if you feel unwell"]
+
+---
+
+### Type C: Test Results Letter
+
+**Your [test name] results — [Normal / Abnormal] — stated in the FIRST sentence, never paragraph 3.**
+
+[What this means in plain English]
+
+**What happens next:** [Clear next steps. If no action, say so explicitly.]
+
+---
+
+## Plain Language Rules (apply to all types)
+- Maximum 2 syllables per word where possible
+- Maximum 20 words per sentence
+- Active voice: "We will contact you" not "You will be contacted"
+- Spell out all acronyms on first use
+- No Latin: "twice daily" not "bd"
+- Use "you" and "we" throughout
+- Numbers as digits: "2 tablets" not "two tablets"
+
+## Quality Checks
+
+- [ ] Written at or below Grade 8 reading level (short words, short sentences)
+- [ ] Active voice used throughout ("We will contact you" not "You will be contacted")
+- [ ] Results letter states the result in the first sentence
+- [ ] Next steps are specific and include timeframes
+- [ ] No Latin or acronyms without explanation
+- [ ] Disclaimer that clinical review is required before sending
+
+## Anti-Patterns
+
+- [ ] Do not use medical jargon without a plain-English explanation — write for the patient, not the clinician
+- [ ] Do not omit a clear "next steps" section — patients must know exactly what to do after reading
+- [ ] Do not produce final content without flagging that clinical review is required before sending
+- [ ] Do not write above a Grade 8 reading level without a compelling reason — accessibility is the default
+- [ ] Do not include Latin abbreviations (e.g. "p.r.n.", "b.d.") without spelling them out — they are not universally understood
+
+## Example Trigger Phrases
+- "Write a patient letter about [topic]"
+- "Create a patient information leaflet for [procedure]"
+- "Write a plain English results letter for [test]"
