Introduce runtime scheduling of per-row LoRA strengths. Adds h3lora/schedule.py (Schedule, ScheduleState, parsing, progress_from), new H3LoraSchedule node in nodes.py, and wiring in apply.py to resolve per-row schedules and preserve bias deltas. branch.py extended with FusedBranch, schedule-aware fusion, LoraBank/LoraBranch changes, and ScheduleController wrapper (attach now returns controller). README updated and unit tests added (tests/test_schedule.py, tests/test_branch_schedule.py) to validate curves, domains, thread-local state and controller nesting.
