fix(docker): clone platform from git instead of additional_contexts

The additional_contexts approach required cc-platform-core to exist on
the Docker host at a relative path. This fails on servers where the
repo layout differs. Instead, use a multi-stage build: stage 1 clones
cc-platform-core from Gitea (depth 1), stage 2 copies server/ into the
app and rewrites the file: path. Fully self-contained — no host deps.
Applied to both production and dev Dockerfiles.

 **GPS not working?**
 - Set up 4 GPS host computers at high altitude
 - Run `gps host X Y Z` on each (with their coordinates)
+- **Alternative:** If running Opus OS, use its `gpsServer` package — a single
+  turtle can self-build a complete GPS constellation (replaces 4 host computers)
+
+## Pathfinding
+
+The turtle now includes a built-in pathfinding module exposed as `_G._pathfind`.
+You can trigger it from the web UI via eval commands:
+
+```lua
+-- Navigate to coordinates (avoids obstacles)
+_pathfind.goto(100, 65, -200)
+
+-- Navigate with block digging enabled
+_pathfind.goto(100, 65, -200, { dig = true })
+
+-- Go home
+_pathfind.goHome()
+
+-- Face a specific heading (0=south, 1=west, 2=north, 3=east)
+_pathfind.face(3)
+
+-- Get current heading name
+_pathfind.headingName()  -- "east"
+```
+
+The pathfinder:
+- Uses GPS for initial position, then tracks movement locally
+- Auto-detects heading on startup via GPS triangulation
+- Handles obstacles by trying to go over/around them
+- Supports optional block digging for clearing paths
