landing(install): two real paths (Start9 vs from source); honest tier framing

- Restructure the Install section to the correct axis: Option 1 (recommended)
  is the packaged service on Start9 (marketplace or sideload the s9pk); Option 2
  is running the daemon from source on any Linux box / VPS. Both are self-hosting.
- Fix the sideload asset name: keysat.s9pk (was keysat_x86_64.s9pk).
- State the free-Creator-tier funnel on the source card; soften the Start9 CTA
  from "Then activate your license" to "Want more than the Creator tier?" so both
  paths tell the same free-to-start, buy-to-expand story.
- Example-prompt lead-in now acknowledges provisioning (one-click on Start9, or
  the agent clones + launches), instead of assuming a running instance.
