flickies v0.3.0 — frame-accurate `precise` flag on trim + concat New optional `precise: bool` (default `false`) on: POST /v1/video/trim POST /v1/video/concat (plus the matching MCP tools) When false: keeps the existing `-c copy` stream-copy fast path. When true: re-encodes (libx264 CRF 18 / AAC 192k) for frame-accurate boundaries — fixes start_sec snapping to the nearest keyframe and fixes concat of inputs with mismatched codec/timebase/SAR. Defaults preserve prior behavior exactly. Pure additive change. Spec info.version bumped to 0.3.0; Pydantic + Python clients regenerated.
