feat(verified): evidence chain -- change, run and evidence identities

[gHashTag]

Closes #6692
Refs #6655 (Phase D: change identity, run identity, evidence record)

Adds specs/verified/evidence_chain.t27. chain(change, run_change, run, ev_run, has_outputs, has_tests, has_logs, seal) checks the links in order and returns LINKED or the first broken one:

• the change has an id;
• the run is bound to this change;
• the evidence is bound to this run;
• the evidence references outputs, tests and logs;
• the seal matched.

A record that points at another change or run is a different chain, so it proves nothing about this one. Missing is never linked. Ids are 64-bit prefixes of existing hashes and numbers, so no hash is computed and no new store is added.

Evidence (Railway lab, master t27c, zig 0.16.0):

• 9/9 tests passed
• 10/10 mutants killed
• gen-verilog (145 lines) and gen-c (155 lines) OK
• t27c seal --verify: all hashes MATCH (spec_hash sha256:661844eb...)
• gitleaks: no leaks; own-language hook passed
