v3.0.13 — character LoRA fixes

Two bug fixes in the character / LoRA path — both reported by @claude3d in #5 and validated end-to-end before shipping.

Fixed

• Character LoRA with a space in its filename (e.g. Annie Phosphene_v2.safetensors) was misclassified as a style-only LoRA, and the Character tab showed "No trained characters yet" — even when the sidecar was correct. The id-validation regex rejected spaces and gated the character scan before the sidecar was read. Spaces are now allowed end-to-end — classification, selection, and the /characters/<id>/… routes — so multi-word character names work with no renaming.
• Character tab silently rendering plain text-to-video. Switching away from the Character tab and back left the avatar's selection ring lit while the underlying selection had been cleared — so Generate shipped no character and you got a plain T2V clip with the trigger doing nothing. The selection indicator now stays in lockstep with the actual selection, so a character that looks selected really is. (For reference: the Params panel showing "Text" is by design — the character_id drives the LoRA stack, not the mode label.)

Also

• The prompt Enhance feature now correctly preserves the active character trigger token.
