feat: modernize plugin to v8.1.0 with full Claude Code spec compliance

- Fix "agents: Invalid input" installation error by stripping non-standard
  frontmatter keys from all 36 agents, 41 commands, and 27 skills
- Replace legacy path discovery with ${CLAUDE_PLUGIN_ROOT} across 81 files
- Remove ~230 lines of dead Python code from orchestrator system prompt
- Add missing SKILL.md for transcendent-ai-systems skill
- Fix YAML parse errors in 3 commands and normalize tool format
- Remove invalid model: inherit from 25 agent files
- Update all documentation for v8.1.0 release

+### Fixed
+- **Installation Error**: Resolved "agents: Invalid input" validation error preventing marketplace installation
+- **Agent Frontmatter**: Stripped non-standard keys (group, group_role, category, tier, version, usage_frequency, common_for, examples) from all 36 agents
+- **Command Frontmatter**: Fixed 3 commands with broken YAML (missing --- delimiter), quoted special characters, removed non-standard keys from 8 commands
+- **Skill Frontmatter**: Added missing SKILL.md for transcendent-ai-systems, removed non-standard keys from 4 skills
+- **Invalid Model Values**: Removed `model: inherit` from 25 agents (not a valid plugin spec value)
+- **YAML Parse Errors**: Fixed orchestrator.md and quality-controller.md YAML parsing failures caused by unicode arrows
+
+### Changed
+- **Path Modernization**: Replaced `python lib/` and `<plugin_path>` with `${CLAUDE_PLUGIN_ROOT}/lib/` across 81 files
+- **Orchestrator Cleanup**: Removed ~230 lines of dead Python import/subprocess code from orchestrator.md system prompt
+- **Plugin Manifest**: Removed explicit agents/commands/skills path declarations from plugin.json (relies on auto-discovery)
