chore: bump fizeau to v0.14.46

Native-API claude transport (default-off FIZEAU_CLAUDE_TRANSPORT knob;
subprocess remains default), claude-tui spec-compliance test hardening
(8 new tests), Gate-E billing-observation harness, and ADR-013 disposition.
No production routing behavior change: claude-tui stays the flat-rate
default; native claude is opt-in metered transport.
