chore: relocate Steelbore sibling-project URLs to Steelbore org

Sibling Steelbore projects referenced from Caliper docs have moved
from the personal namespace to the Steelbore org:

- `github.com/UnbreakableMJ/rust-guidelines`
  -> `github.com/Steelbore/rust-guidelines`
- `github.com/UnbreakableMJ/steelbore-standard`
  -> `github.com/Steelbore/steelbore-standard`

Affects PRD.md (references section), PLAN.md (references),
CONTRIBUTING.md (code style link), CREDITS.md (third-party row).

`Research/caliper-foundry-PRD.md` is a historical snapshot and is
left untouched. `flake.nix` still references
`github:UnbreakableMJ/bravais` in a v1.0.0 comment -- bravais will
move in a separate change once its canonical home is confirmed.
