feat(ecc): prune plugin 43→12 items, promote 7 rules to .claude/rules/ (#245)

ECC community plugin pruning: removed 530+ non-essential files
(.cursor/, .opencode/, docs/ja-JP, docs/zh-CN, docs/zh-TW,
language-specific skills/agents/rules). Retained 4 agents,
3 commands, 5 skills. Promoted 13 rule files (8 common + 5
typescript) to .claude/rules/ for CC native loading. Extracted
reusable patterns to EXTRACTED-PATTERNS.md.

-# Instinct Status Command
-
-Shows all learned instincts with their confidence scores, grouped by domain.
-
-## Implementation
-
-Run the instinct CLI using the plugin root path:
-
-```bash
-python3 "${CLAUDE_PLUGIN_ROOT}/skills/continuous-learning-v2/scripts/instinct-cli.py" status
-```
-
-Or if `CLAUDE_PLUGIN_ROOT` is not set (manual installation), use:
-
-```bash
-python3 ~/.claude/skills/continuous-learning-v2/scripts/instinct-cli.py status
-```
-
-## Usage
-
-```
-/instinct-status
-/instinct-status --domain code-style
-/instinct-status --low-confidence
-```
-
-## What to Do
-
-1. Read all instinct files from `~/.claude/homunculus/instincts/personal/`
-2. Read inherited instincts from `~/.claude/homunculus/instincts/inherited/`
-3. Display them grouped by domain with confidence bars
-
-## Output Format

-## Flags
-
-- `--domain <name>`: Filter by domain (code-style, testing, git, etc.)
-- `--low-confidence`: Show only instincts with confidence < 0.5
-- `--high-confidence`: Show only instincts with confidence >= 0.7
-- `--source <type>`: Filter by source (session-observation, repo-analysis, inherited)
-- `--json`: Output as JSON for programmatic use
