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.

+# Discovery Interview Guide Skill
+
+Design interviews that surface genuine insight — not validation of what you already believe. Every guide follows a story-based, past-behaviour-focused structure.
+
+## Core Principles
+
+1. **Never ask about the future.** "Would you use X?" tells you nothing. "Tell me about the last time you did X" tells you everything.
+2. **Interview for behaviour, not opinion.** Opinions are cheap. Behaviour is evidence.
+3. **The 5 Whys.** Every surface answer is a door. Keep opening doors.
+4. **Confirm the problem before exploring the solution.** Never show a prototype until you've confirmed the pain exists unprompted.
+
+## Interview Structure (60 minutes standard)
+
+### 1. Warm-Up (5 min)
+Build rapport. Get them talking. Don't discuss the topic yet.
+- "Tell me a bit about your role and what a typical week looks like for you."
+- "What tools do you rely on most day-to-day?"
+
+### 2. Context Setting (10 min)
+Understand their world before diving into the problem space.
+- "Walk me through how you currently [handle the domain area]."
+- "What does that process look like from start to finish?"
+- "Who else is involved when you do this?"
+
+### 3. Problem Exploration (25 min) — THE CORE
+Surface pain without leading.
+- "Tell me about the last time you had to [relevant task]. What happened?"
+- "What was the hardest part of that?"
+- "How did you handle it?"
+- "What did you try before settling on that approach?"
+- "What does it cost you when this goes wrong?" (time, money, stress, reputation)
+- "If you could wave a magic wand and change one thing about this process, what would it be?"
+
+⚠️ **Do not mention your product or feature during this phase.**
+
+### 4. Current Solutions (10 min)
+Understand the competitive landscape from their perspective.
+- "What tools or workarounds do you use today for this?"
+- "What do you like about [current solution]? What frustrates you?"
+- "Have you tried other approaches? What happened?"
+
+### 5. Wrap-Up (10 min)
+- "Is there anything about this topic we haven't covered that you think I should know?"
+- "Is there anyone else you'd recommend I speak to?"
+- "Would you be open to a follow-up if I have more questions?"
+

+
+## Output Format
+
+### Discovery Interview Guide — [Topic] — [Date]
+
+**Research Goal:** [One sentence: what decision will this research inform?]
+**Target Participant Profile:** [Role, company size, behaviour qualifier]
+
+**Screener Questions** (for recruiting):
+1. [Question] → Must answer: [Y/N or specific]
+2. [Question] → Must answer: [Y/N or specific]
+3. [Disqualifier question] → Disqualify if: [answer]
+
+**Interview Guide:**
+
+[Full structured guide using the format above, customised to the specific research topic]
+
+**Synthesis Template** (fill after each interview):
+- Key quote: "[verbatim]"
+- Core pain: [1 sentence]
+- Current workaround: [what they're doing today]
+- Intensity (1–5): [how painful is this?]
+- Surprise/unexpected finding: [anything that challenged your assumptions]
+
+**Pattern Detection** (after 5+ interviews):
+- Pain mentioned by [X/N] participants: [theme]
+- Workaround used by [X/N] participants: [theme]
+- Most emotionally charged moment in interviews: [observation]
+
+---
+
+## Required Inputs
+
+Ask the user for these if not provided:
+- **Research topic or question** (what decision will this inform?)
+- **Target participant profile** (role, behaviour, company type)
+- **Session length** (30 / 45 / 60 / 90 minutes)
+- **Number of interviews planned**
+- **Known hypotheses to test or avoid confirming prematurely** (optional)
+
+## Quality Checks
+
+- [ ] No future-tense questions ("would you...") — only past-behaviour questions
+- [ ] Product or solution not mentioned until after pain is confirmed
+- [ ] Questions open-ended (cannot be answered yes/no)
+- [ ] Synthesis template included for per-session notes
+- [ ] Screener questions identify and disqualify wrong participants
+
+## Guidelines
+
+- Recommend 5–8 interviews to reach thematic saturation for most discovery questions
+- Always record with permission — transcripts beat notes
+- If user is new to interviewing: remind them to stay silent after asking a question (aim for 80/20 participant-to-interviewer talking ratio)
+- Never synthesise during the interview — do it after, when you can look across sessions
+- Flag confirmation bias: if user writes questions that lead toward a predetermined answer, rewrite them as open-ended alternatives
+
+## Anti-Patterns
+
+- [ ] Do not use future-tense questions ("Would you use this?") — hypothetical responses do not predict real behaviour and produce false confidence in an idea
+- [ ] Do not mention your product or solution before problem exploration is complete — doing so anchors the participant's responses and invalidates the discovery
+- [ ] Do not synthesise across fewer than 5 interviews — themes from 2–3 interviews reflect anecdote, not pattern; wait for saturation
+- [ ] Do not write screener questions that are too easy to pass — if participants can guess the "right" answer, you will recruit the wrong people
+- [ ] Do not treat participant opinions as evidence of future behaviour — what people say they will do consistently diverges from what they actually do
