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.

+# Debugging Log Analyser Skill
+
+Parses raw error logs, stack traces, and crash reports into a structured diagnosis with probable root cause, affected code path, and specific next steps — no hand-waving.
+
+## Required Inputs
+
+Ask for these if not provided:
+- **The log / stack trace / error output** (paste directly or describe the error)
+- **Language and framework** (e.g. Node.js + Express, Python + Django, Java Spring, Go)
+- **Context** (what changed before this started — e.g. recent deploy, config change, increased traffic, new input data; or "nothing changed" is also useful)
+- **Frequency** (one-off / intermittent / consistent / regression after a specific change)
+- **Environment** (local dev / staging / production)
+- **What they've already tried** (if anything)
+
+## Output Format
+
+---
+
+# Debugging Report: [Service/App Name]
+
+### 1. Error Classification
+**Error type:** [Runtime exception / Build error / Config error / Network error / Memory error / Unknown]
+**Severity:** [Fatal / Critical / Warning / Informational]
+**Recurrence pattern:** [One-off / Intermittent / Consistent / On-startup / Under load]
+
+### 2. Stack Trace Analysis
+
+Walk the stack frame by frame, starting from the origin:
+- **Origin frame:** [File, line, function where it started]
+- **Propagation path:** [How it travelled through the call stack]
+- **Crash point:** [Where it ultimately threw/panicked/exited]
+
+For each significant frame, note whether it is:
+- User code (fixable here)
+- Framework/library code (usually a misuse issue)
+- System/runtime code (usually a config or environment issue)
+
+### 3. Root Cause Assessment
+**Probable root cause:** [1–2 sentence plain English statement]
+**Confidence:** [High / Medium / Low — and why]
+**Alternative causes to rule out:** [If confidence is not high]
+
+### 4. Affected Code Path
+**Entry point:** [Where the triggering call began]
+**Key function(s) involved:** [Specific functions/methods named in the trace]
+**Data that triggered it:** [If inferable from the log — e.g. null value, malformed JSON]
+
+### 5. Suggested Fix
+Provide a concrete, code-level suggestion:
+- What to change (the minimal fix)
+- Why this fixes the root cause
+- Any trade-offs or risks in the fix
+- A short code snippet if helpful
+
+### 6. Next Debugging Steps
+If the root cause is uncertain, provide an ordered list of 3–5 specific debugging actions:
+1. [Specific thing to check — file, log line, config value]
+2. [Specific reproduction step or isolation test]
+3. [Specific tool command — e.g. `strace`, `pprof`, `--verbose`, add logging at X]
+
+### 7. Prevention
+One or two concrete things that would prevent this class of error recurring:
+- Better input validation at [point]
+- Add monitoring/alerting for [condition]
+- Test that covers [scenario]
+
+---
+
+## Quality Checks
+- [ ] Root cause is specific (not "there might be a null pointer issue")
+- [ ] At least one concrete code-level fix is suggested
+- [ ] Next steps are actionable commands, not vague advice
+- [ ] Suggested fix references the actual language/framework in the input (not a generic fix that could apply to any language)
+- [ ] Confidence level includes a stated reason (not just "High" or "Low" with no explanation)
+- [ ] Prevention is proactive (not just "add error handling")
+
+## Usage Examples
+- "Why is this crashing?" + [paste log]
+- "Can you analyse this stack trace?"
+- "I'm getting this error, what does it mean?"
+- "Debug this log for me"
+- "What's causing this exception?"
