[Good first issue]: Add a 60-second kaios tour transcript

[morning-verlu]

Goal

Add a short docs walkthrough that shows what a first-time user should see when they run kaios tour.

This should help visitors understand the Evidence OS loop before they install or run anything locally.

Suggested scope

• Add a compact section to docs/LOCAL_TOUR.md or START_HERE.md.
• Show the key output moments, not the full terminal log.
• Include the product mapping: Agent = Process, Tool = Syscall, Run = Evidence, CI = Gate.
• Link to the generated artifacts a user should inspect after the tour.

Verification

For a docs-only PR, run:

git diff --check

If you can run the CLI locally, also run:

./gradlew installDist
build/install/kaios-cli/bin/kaios tour --dir /tmp/kaios-tour-check

Notes

Keep the PR narrow. This should be a beginner-friendly transcript, not a rewrite of the whole onboarding flow.
