feat(cli): add support for dynamic configuration loading via SUPAMEM_PROJECT_ROOT

- Implemented functionality in cmd_mcp_server to utilize the SUPAMEM_PROJECT_ROOT environment variable for loading configurations dynamically.
- Updated documentation to clarify the usage of SUPAMEM_PROJECT_ROOT when running the server outside the repository context.
- Refactored cursor.py to conditionally inject SUPAMEM_PROJECT_ROOT based on the presence of the configuration file in the current working directory.

+description: Use both semantic (qdrant-find) and structural (graphify) memory before non-trivial code changes
+alwaysApply: true

+
+# Dual Memory — supamem
+
+Use **both** memory layers before any non-trivial code change.
+
+## When to query
+
+- New feature, refactor, debugging, or architecture decision
+- Adding/modifying dependencies
+- Code review of a non-trivial change
+
+## Semantic (Qdrant tuned_hybrid)
+
+```
+qdrant-find "<topic> decisions"
+qdrant-find "<topic> known issues"
+qdrant-find "<topic> patterns"
+```
+
+## Refresh
+
+If memory feels stale: `supamem index --target tuned --force`.
+
+## Anti-patterns
+
+- ❌ Querying after coding — check memory before implementing.
+- ❌ Skipping semantic for "what calls X" — use structural for that.
+- ❌ Trusting hits without checking source attribution — always inspect the
+  payload's `source` field.
