* feat: per-model sampling parameters (temperature, max_tokens, reasoning_effort) Model sampling parameters were global-only settings applied uniformly to all models. Different models have fundamentally different requirements (o-series needs no temperature, Anthropic needs temp=1.0 with thinking, local models may need different max_tokens). This adds per-model overrides with global fallback so each model definition can specify its own defaults. Migration 036 adds nullable temperature, max_tokens, reasoning_effort columns to model_definitions. NULL inherits the global default from ConfigStore. The session factory and /model switch command both resolve per-model override → global fallback consistently. The admin UI model create/edit modal now has dedicated form fields for these parameters with client-side validation, a visual section divider, and per-model override hints in the model table rows. Removes vestigial model.name and model.context_window global settings (now handled per-model by the model registry) with startup warnings for existing config.toml users. * fix: defensive parsing for config.toml per-model sampling params Wrap temperature/max_tokens conversions in try/except with range validation. Invalid values log a warning and fall back to None (inherit global default) instead of aborting registry load.
