chore: bootstrap lean sysadmin-chronicles repo

Import the runnable game code, content, docs, scripts, and repo guidance while leaving local agent state, dependency installs, build output, and backup copies out of the published tree.

+# RTK Usage
+
+`rtk` is installed at `/home/aaron/.cargo/bin/rtk`. Use it by default for noisy shell commands so agent sessions spend fewer tokens on low-value output.
+
+Prefer `rtk` for:
+
+- directory and file discovery: `rtk ls`, `rtk tree`, `rtk find`
+- search output: `rtk grep`
+- tests and builds with noisy output: `rtk test`, `rtk npm test`, `rtk tsc`, `rtk lint`
+- dependency and environment summaries: `rtk deps`, `rtk env`
+- logs, JSON, diffs, and command summaries: `rtk log`, `rtk json`, `rtk diff`, `rtk summary`
+
+Use raw shell commands instead when exact, unfiltered, streaming, or interactive output matters. Examples: `sed -n` for precise line ranges, `tail -f` for live logs, `virsh console`, prompts, password entry, TTY tools, and commands whose full output is the thing being inspected.
+
+Examples:
+
+```bash
+rtk ls -la
+rtk tree -L 2
+rtk grep "READY_COMMAND" tools/vm
+rtk npm test
+rtk deps
+```
+
+Useful checks:
+
+```bash
+rtk --version
+rtk gain
+rtk init --codex --show
+```
