refactor: Decompose next_occurrence into per-recurrence functions

[2witstudios]

Summary

• Split monolithic next_occurrence match with 6 inline date-math arms into focused functions (next_daily_occurrence, next_weekly_occurrence, etc.)
• Extract shared naive_at_base_time helper eliminating 3 identical and_hms_opt blocks
• next_occurrence is now a 6-line dispatcher

Baseline (from churn analysis)

Metric	Before
LoC	658
Cx	51
Density	20%

Test plan

• Run cargo test — existing schedule tests validate all recurrence types
• Run npx aidd churn to compare metrics
