Fix Repainting Pine Script Alerts

My TradingView bot is intermittently skipping critical Stop-Loss alerts, firing others at the wrong time, and occasionally throwing vague script errors. Support pointed to repainting as the root cause, and after a few live tests I can confirm the behavior: signals look fine on the chart after the fact, yet real-time alerts sometimes never trigger or trigger late.

The task is straightforward: rework the existing Pine Script (currently v5) so every alert I define is delivered in real time, with zero tolerance for missed SL notifications. If eliminating repainting is the cleanest path, great—if not, I still need logic that guarantees the alert fires exactly once per intended bar and never retroactively changes.

Deliverables
• Revised, fully commented Pine Script v5.
• Demonstration (strategy tester or live paper session) showing 100 % capture of Stop-Loss alerts over a representative data window.
• Brief hand-off note summarising what was changed, why the code is now non-repainting (or safely compensates for repainting), and how to add future alerts without breaking this guarantee.

Acceptance criteria: during a shared screen session or video proof, the script must run for at least 100 bars on multiple symbols and timeframes with no missed or double-fired SL alerts.

I keep the rest of the strategy logic intact; only alert reliability is critical.
