fix(bridge): v0.3.11 approval flow architecture fix — eliminate double-fire auto-approve, strip 30+ failed RPC strategies, add project_name DEDUP guard

- Remove Extension-side auto-approve (was double-firing with Bot auto-approve)
- Strip failed strategies 0A-1 from tryApprovalStrategies (~150 lines)
- Keep only Strategy 0-PROTO (proto RPC) + Strategy 2 (clickTrigger)
- Add bot.py AUTO-RESOLVED logging for diagnostics
- Update known-issues with 3 new entries
- Clean deployment: v0.3.8→v0.3.10→v0.3.11
