v1.2.3

Summary

All code review findings have been addressed, unit tests added, and the CoinGecko API integration has been hardened.

🐛 Bug Fixes

Alert System

• alert remove now removes all alerts for a given coin
• Triggered alerts remove only themselves (other alerts for the same coin are preserved)
• Alert price comparison respects the --currency flag
• Negative and invalid price/condition inputs are rejected

Portfolio

• Coin IDs are normalized to lowercase (fixes case-sensitivity duplicates)
• Negative amount and price values are rejected
• Zero balances are removed from holdings after a full sell
• Transaction currency is stored; history view shows the correct symbol

⚡ Performance

• Portfolio list uses a single batch API call (GetMarketsByIDs)
• Removed duplicate API call when fetching coin details

🔒 Security

• ~/.crypto/portfolio.json and alerts.json are written with 0600 file permissions

🛠 Infrastructure

• Search queries are URL-encoded
• Added retry/backoff for CoinGecko 429 rate limit responses
• page / per-page flags validate input (range 1–250)
• Alert checker has safe start/stop lifecycle; runs only when active alerts exist

15 new unit tests added across models, service, and utils.
