The `MinimumPoints` field still exists as a manual config value (`\"minimum-points\"` in JSON), but it's redundant — since we now always have a policy (user pref or default), the target points from that policy are the natural minimum threshold for resampling.\n\nThe resampler library (`cc-lib/v2/resampler`) has a global `MinimumRequiredPoints` (default 1000) set via `SetMinimumRequiredPoints()`. Currently this is set in `config.Init()` only when `minimum-points > 0` in config.json.\n\n**Goal**: Remove `MinimumPoints` from config and derive it automatically from the default policy's target points (low=200, medium=500, high=1000).\n\n## Changes\n\n### 1. `internal/config/config.go`\n- Remove `MinimumPoints int` field from `ResampleConfig`\n- In `Init()`: replace the `MinimumPoints > 0` check with policy-derived logic:\n - Use `metricdispatch.TargetPointsForPolicy()` on `DefaultPolicy` (or \"medium\" if empty) to get the target points\n - Call `resampler.SetMinimumRequiredPoints(targetPoints)`\n- This requires importing `metricdispatch` — need to check for import cycles\n\n**Import cycle concern**: `config` is imported by almost everything. `metricdispatch` imports `config`. So `config` cannot import `metricdispatch`.\n\n**Solution**: Inline the policy→targetPoints mapping in `config.Init()` instead of calling `metricdispatch.TargetPointsForPolicy()`.
