Two ready specs can collide

Lifecycle approvedImplementation completeVerification unknownQualification unknown

`registry plan` answers "what can be worked on now", and a scheduler fans that answer out. Readiness is computed from `depends_on` alone, so two specs with no edge between them are both offered even when they claim the same files. The corpus has the case standing today: drafts 084 and 085 both extend `crates/spec-spine-cli/src/verify_attestation.rs`, `attest.rs` and `lib.rs`, neither depends on the other, and `plan` lists both as ready with no way to say so. This spec adds the overlap report: for every pair on the ready set, the units both claim. It is a report and never a refusal, and it is a lower bound rather than a safety verdict: disjoint territory does not prove independence, because a shared lockfile, a regenerated shard or a consumed API are collisions no frontmatter declares. `plan` keeps exiting 0.
