♻️ refactor: migrate AI Rules to Claude Code Skills system
Migrate all AI Rules from .cursor/rules/ to .agents/skills/ directory:
- Move 23 skills to .agents/skills/ (main directory)
- Update symlinks: .claude/skills, .cursor/skills, .codex/skills
- Create project-overview skill from project documentation
- Add references/ subdirectories for complex skills
- Remove LobeChat references from skill descriptions
- Delete obsolete .cursor/rules/ and .claude/commands/prompts/ directories
Skills structure enables better portability and maintainability across AI tools.

Build Index Maps for Repeated Lookups
Multiple .find() calls by the same key should use a Map.
Incorrect (O(n) per lookup):
function processOrders(orders: Order[], users: User[]) {
return orders.map(order => ({
...order,
user: users.find(u => u.id === order.userId)
}))
}
Correct (O(1) per lookup):
function processOrders(orders: Order[], users: User[]) {
const userById = new Map(users.map(u => [u.id, u]))
return orders.map(order => ({
...order,
user: userById.get(order.userId)
}))
}
Build map once (O(n)), then all lookups are O(1). For 1000 orders × 1000 users: 1M ops → 2K ops.
