feat: Fibonacci Trust Milestone System #7

Replace linear trust thresholds with Fibonacci milestones.
fib=[2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597]
nextTrust=fib[n]*1000

Each milestone:
- Logs a narrative message (educational: exponential growth)
- Grants a small permanent bonus (ops rate, trust rate, boosts)
- Shows particle burst on trust resource
- Progress indicator in trust resource display

15 milestones total. Educational: Fibonacci growth feels natural
because it IS natural — spiral shells, sunflower seeds, galaxies.

Closes #7
