feat(content): author the ROOT_ V1 orientation module and three practice-bank intro lessons

- root-01-m00-welcome-to-root: program overview + Lab-lifecycle orientation (disposable Labs, permanent progress, hints, reset/recreate, help-requests). - One short intro-lesson activity for each of the three bare practice-bank modules (root-06-m01, root-07-m01, root-10-m02), explaining what the bank is and why it has no per-scenario teaching of its own — the minimum real authoring needed for genuine self-paced readiness without reclassifying them optional (see the curriculum migrations).

+# Practice Bank: General Troubleshooting Operations
+
+**Kubernetes Health Probes & Troubleshooting** and **The RootNode Troubleshooting Framework**
+already taught you how to *think* about a broken cluster. This module is six short Labs that
+drill the individual `kubectl` operations you'll reach for while doing that thinking: pulling
+logs, copying files in and out of a container, running a one-off exec, cordoning a node, and
+reasoning about pod-to-node placement and log output.
+
+## How to use it
+
+Work through the six Labs in order. None of them require the full Observe/Evidence/Hypothesis/
+Test/Repair/Validate/Prevent framework from the previous module — they're deliberately narrower,
+so you can build raw command fluency without also holding the whole framework in your head at
+the same time.
+
+## Instructor Notes
+
+**Delivery:** No lesson/demonstration/knowledge-check scaffolding by design — this is the
+original Phase 1-5 "troubleshooting" scenario bank plus one extra Lab (`container-logging-mcq`)
+not part of that original set, reused here as self-paced speed practice.
+
+**Capstone note:** The five original Labs (`extract-logs-basics`, `kubectl-cp-basics`,
+`exec-command-basics`, `node-cordon-basics`, `pod-node-assignment-mcq`) are the exact set the
+pre-existing `rootnode-path.json` "troubleshooting" stage requires to unlock the Capstone
+assessment — a separate, older mechanism from this course's own prerequisite chain (see
+docs/ROOT_V1_CURRICULUM_MANIFEST.md). Do not mark this module optional/is_required=false without
+re-checking that gate.
+
+**Common mistake to watch for:** running `kubectl cp` with the source/destination arguments
+reversed — a good moment to have a student read the command back out loud before running it.
