feat: v2.0.0 - Domain-based memory + multi-plugin marketplace structure

## Domain-based Memory (v2.0.0)
- Memory split into domains (backend, frontend, database, testing, deployment, global)
- Selective loading via `paths` frontmatter - only relevant memories load
- Automatic domain detection from file paths in conversation
- Auto-generated glob patterns when creating new domains
- Cross-domain analysis in /learn:reflect

## Repository Reorganization
- Restructured for multi-plugin marketplace: plugin/ → plugins/learn/
- Marketplace renamed: romfast-tools → romfast-plugins
- Repository to be renamed on Gitea: claude-learn → claude-plugins

+## [2.0.0] - 2026-01-06
+
+### Changed (Repository)
+- **Reorganized for multi-plugin marketplace**: `plugin/` → `plugins/learn/`
+- Repository to be renamed: `claude-learn` → `claude-plugins`
+- Updated marketplace.json source path
+
+### Added
+- **Domain-based memory**: Memory is now split into domains (backend, frontend, database, testing, deployment, global)
+- **Selective loading via `paths` frontmatter**: Each domain file has a `paths:` frontmatter that triggers loading only when working with matching files
+- **Automatic domain detection**: `/learn:analyze` detects the domain based on file paths in the conversation
+- **Automatic pattern suggestion**: When creating new domains, glob patterns are auto-generated from conversation files
+- **Cross-domain analysis**: `/learn:reflect` now analyzes duplicates and misplaced entries across domains
+- **Domain configuration file**: `.claude/rules/claude-learn-domains.md` for user-editable domain definitions
+- New templates: `domains-config.md`, `domain-memory.md`
+
+### Changed
+- `/learn:analyze` now prompts for domain confirmation before saving
+- `/learn:status` aggregates statistics from all domain files with breakdown table
+- `/learn:import` routes entries to appropriate domains with detection
+- `/learn:reflect` includes cross-domain duplicate detection and domain migration suggestions
+- Memory files now use format `claude-learn-{domain}.md` instead of single `claude-learn-memory.md`
+
+### Migration
+- Run `/learn:import .claude/rules/claude-learn-memory.md` to migrate from v1.0 format
+- Old format is auto-detected and migration is offered
+
