Deduplicate README structure list and add consistency lint

README no longer mirrors the contract list; the bootstrap router is the
single source of truth. scripts/lint.sh checks router coverage, dead
bootstrap references, and machine-local absolute paths.

+The list of contracts is not duplicated here. The single source of truth for what exists
