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.

+
+# Content Calendar Skill
+
+This skill generates a structured content calendar from brand inputs. It produces ready-to-use calendar entries with topics, formats, channels, and opening hooks — usable for social media, blogs, newsletters, or multi-channel campaigns.
+
+## Required Inputs
+
+Ask the user for these if not provided:
+- **Brand or product name**
+- **Target audience** (who are you trying to reach?)
+- **Primary content goal** (awareness / lead gen / retention / thought leadership)
+- **Channels** (e.g. LinkedIn, Instagram, newsletter, blog, X/Twitter)
+- **Cadence** (daily / 3x per week / weekly / monthly)
+- **Timeframe** (e.g. 4 weeks, Q2)
+- **Brand pillars or themes** (optional — if not provided, derive 3 from the product description)
+
+## Output Structure
+
+### 1. Content Pillars (if not provided)
+
+Derive 3–4 content pillars from the brand/product description. Each pillar = a recurring theme that anchors multiple posts. Label each one clearly (e.g. "Pillar 1: Industry Education", "Pillar 2: Product Stories").
+
+### 2. Calendar Table
+
+Produce a weekly table for each week requested. Format:
+
+| Date | Pillar | Topic | Format | Channel | Opening Hook |
+|---|---|---|---|---|---|
+| Mon 7 Apr | Education | [Topic title] | Carousel / Article / Short video / Thread | LinkedIn | [First sentence or headline of the post] |
+
+Rules:
+- Rotate through all pillars across the week — don't stack the same pillar on consecutive days
+- Match format to channel norms (e.g. carousels for Instagram, long-form for LinkedIn, threads for X)
+- Opening hooks must be specific and scroll-stopping — no generic openers like "Did you know..."
+- Flag 1–2 posts per week as "High Priority" — these are the cornerstone pieces worth boosting or repurposing
+
+### 3. Repurposing Map
+
+For each "High Priority" post, add one repurposing suggestion — e.g. "Turn this LinkedIn article into a newsletter section" or "Clip this video for an Instagram Reel."
+
+## Quality Checks
+
+- [ ] Every week has balanced pillar distribution
+- [ ] No two consecutive posts have the same format on the same channel
+- [ ] Opening hooks are specific (no generic openers)
+- [ ] Formats match platform norms
+- [ ] Repurposing map covers all High Priority posts
+
+## Anti-Patterns
+
+- [ ] Do not fill the calendar with generic topic placeholders — every entry must have a specific, usable topic and hook
+- [ ] Do not stack the same pillar or format on consecutive days — variety is required
+- [ ] Do not produce opening hooks that start with "Did you know" or other cliché openers
+- [ ] Do not ignore channel norms — formats must match the platform (no long-form threads for Instagram)
+- [ ] Do not skip the repurposing map for High Priority posts
+
+## Example Trigger Phrases
+
+- "Build me a 4-week content calendar for [brand]"
+- "Create a social media plan for [product launch]"
+- "Give me a monthly editorial calendar for my newsletter"
+- "Plan my LinkedIn content for the next month"
