feat(ttp): E.3.13 IdentityLifter + CredentialLifter (R0001-R0006)

IdentityLifter owns lifter:identity_* — currently R0003 (password
spraying). CredentialLifter owns lifter:credential_* — R0001 generic
auth brute, R0002 password guessing, R0004 credential reuse, R0005
valid-account use, R0006 default credentials.

YAMLs R0001/R0002/R0003/R0005/R0006 had their match.kind normalised
to fit the lifter prefix scheme — the design doc's promised "YAMLs
normalised in a separate refactor commit" lands here.

Identity-rollup tags null out attacker_uuid on emit so the worked-
example invariant holds (the tag belongs to the Identity, never to
one member IP).

Tests: test_identity_lifter.py + test_credential_lifter.py cover
each predicate's positive/negative path, state modulation
(disabled/clipped/expired), source-kind gating, and idempotent
replay. test_lifter_absence and test_lifters updated for the new
ctor signature.
