refactor(linkedin)!: rename plugin linkedin-thought-leadership → linkedin-studio (v3.0.0)

BREAKING CHANGE: the marketplace slug, the agent namespace
(linkedin-studio:<agent>), and the runtime state-file path
(~/.claude/linkedin-studio.local.md) all change. Reinstall required;
existing state migrated in place (post metrics, streak, history preserved).
The /linkedin:* commands are unchanged — the command namespace is set
per-command in frontmatter and was always independent of the plugin slug.
Functionality is byte-identical to v2.4.0; this release is pure identity.

- dir + manifests: plugins/linkedin-studio + plugin.json + root marketplace.json
- agent namespace updated in commands/newsletter.md (only functional invoker)
- state path updated in 4 hook scripts + topic-rotation prompt + state template
- catch-all skill dir renamed skills/linkedin-studio (5 functional skills unchanged)
- docs + version bump to 3.0.0 across README badge, CHANGELOG, root README/CLAUDE.md
- historical records (CHANGELOG past entries, docs/ build artifacts,
  config-audit v5.0.0 snapshots) intentionally retain the old slug

+# Personal LinkedIn Assets
+
+This folder contains YOUR personalized content, frameworks, and insights that make this skill uniquely valuable to you.
+
+## How Assets Are Used
+
+When you ask Claude to create content, it will:
+1. Check your PERSONALIZATION SETTINGS in SKILL.md
+2. Reference relevant assets from these folders
+3. Blend your authentic voice/examples with LinkedIn best practices
+4. Generate content that sounds like YOU, optimized for the algorithm
+
+## Folder Structure
+
+### `/examples/`
+Store your best-performing posts for pattern analysis. Claude will study these to understand what works for YOUR audience and replicate those patterns in new content.
+
+### `/templates/`
+Your custom post templates. When you develop a structure that works consistently, save it here so Claude can apply it to new content.
+
+### `/frameworks/`
+Your proprietary frameworks, models, and methodologies. When creating content, Claude will reference YOUR frameworks instead of generic ones.
+
+### `/case-studies/`
+Real examples from your work. Claude uses these for credibility and specificity instead of making up generic scenarios.
+
+### `/research/`
+Industry research, data, and trends specific to your domain. Helps Claude create data-driven posts with current, relevant information.
+
+### `/voice-samples/`
+Examples of your authentic writing from various contexts. Claude analyzes these to match your natural voice and style.
+
+### `/audience-insights/`
+Your analytics, demographics, and engagement patterns. Claude uses this to optimize content for YOUR specific audience, not generic best practices.
+
+### `/competitors/`
+Analysis of peers and influencers in your space. Helps identify content gaps and opportunities for differentiation.
+
+## Maintenance Schedule
+
+### Weekly (5 minutes)
+- Add your best post from the week to `/examples/`
+- Update posting time insights in `/audience-insights/engagement-patterns.md`
+
+### Monthly (15 minutes)
+- Analyze patterns in `/examples/` and document learnings
+- Update demographics in `/audience-insights/` based on LinkedIn analytics
+- Add any new frameworks developed to `/frameworks/`
+
+### Quarterly (30 minutes)
+- Refresh industry data in `/research/`
+- Update competitor analysis in `/competitors/`
+- Review and refine voice samples in `/voice-samples/`
+
+## Priority Hierarchy
+
+If there's a conflict between:
+- Generic best practices (in `/references/`)
+- Your personal patterns (in `/assets/`)
+
+→ Claude will prioritize YOUR patterns (with optimization suggestions if needed)
+
+**Exception:** If your patterns actively harm algorithmic reach (external links, engagement bait), Claude will flag this and suggest alignment with platform mechanics while maintaining your authentic voice.
+
+## Getting Started
+
+1. **Week 1:** Fill in PERSONALIZATION SETTINGS in SKILL.md (15 minutes)
+2. **Week 2-4:** Add 2-3 voice samples to `/voice-samples/` (20 minutes)
+3. **Month 2:** Start populating `/examples/` with your successful posts (ongoing)
+4. **Month 3:** Add frameworks and case studies as they develop (ongoing)
+
+The more you populate these folders, the more personalized and valuable this skill becomes. Think of it as a system that learns YOUR patterns over time.
