Drop tensorflow deps; rule cleanups; repo-mem MCP; bump pumpingStation@6ab585b

- package.json: remove @tensorflow/tfjs and @tensorflow/tfjs-node.
  Monster's TF code was already stripped; the deps were stale and kept
  pulling a heavy native binary back into every install.
- .gitignore: ignore .repo-mem/ regenerable indexes and per-session
  .claude/*.lock runtime files.
- CLAUDE.md: prepend READ-FIRST pointer to .claude/rules/repo-mem.md;
  collapse the 'three outputs' bullet to a pointer at node-architecture.
- .claude/rules/telemetry.md: drop Port 0/1/2 duplication; reference
  node-architecture.md.
- .claude/rules/testing.md: stop requiring a separate test/edge tier and
  the basic/integration/edge example flow trio. Reflects what nodes
  actually do.
- .claude/rules/repo-mem.md (new): when-to-call-which guide for the
  per-repo memory MCP, anti-patterns, refresh model.
- .mcp.json (new): wire repo-mem stdio server.
- docs/DEVELOPER_GUIDE.md (new): step-by-step guide for adding a new
  EVOLV node under the three-layer pattern.
- Bump nodes/pumpingStation to 6ab585b (docs + simulations refresh,
  spill-flow path renames consistent with d8490aa).

 # EVOLV - Claude Code Project Guide
 
+> **READ FIRST, BEFORE ANY OTHER WORK:** `.claude/rules/repo-mem.md` — this repo has an MCP server (`repo-mem`) exposing a substrate-trained `repo_search` and a persistent fix-trace store. Use those instead of grep for concept queries, and record completed fixes via `repo_record_fix`. Triggers, anti-patterns, and refresh model are in that rule.

 ## What This Is
 Node-RED custom nodes package for wastewater treatment plant automation. Developed by Waterschap Brabantse Delta R&D team. Follows ISA-88 (S88) batch control standard.
