[codex] fix(parser): preserve named Kookus condition

[ntindle]

Summary

Fixes the Root #30 Kookus subcluster in docs/parser-misparse-backlog.md.

Root cause: normalize_card_name_refs only masked card(s) named ... literal spans, so creature named Keeper of Kookus was allowed to self-reference-normalize the embedded source name to Keeper of ~. Then the named-filter terminator did not recognize the post-normalization , ~ ... clause boundary, so the trigger condition swallowed the trigger body into the Named filter.

Changes:

• Extend the existing named-literal mask to object/spell/permanent forms such as creature named, permanent named, spell named, etc.
• Treat , ~ ... as the same referential named-filter boundary class as , it ....
• Add building-block tests and an end-to-end Kookus trigger regression.
• Remove Kookus from Root chore: update coverage stats and badges #30, reducing that bucket from 12 to 11 cards.

Raw changed card keys: exactly kookus.

Expected Kookus movement:

• Named filter changes from keeper of ~, ~ deals 3 damage to you and attacks this turn if able to keeper of kookus.
• The swallowed trigger body now parses as DealDamage { amount: 3, target: Controller } followed by the until-end-of-turn MustAttack continuation.

coverage-parse-diff reported no support-signature clusters (oracle_changed: 0).

Tilt is not running locally (No tilt apiserver found: tilt-default), so direct cargo fallback was used.

Reviewed current head 24df1d582e86e0b37217548ff22cfe90bfb638cd.

The change is at the existing literal-name normalization and named-filter boundary seams, not a Kookus-only parser special case. The parse-diff shows the intended Kookus condition/body repair, with the other listed add/remove entries identical, and the added tests cover both the normalization boundary and the parsed trigger body. No blocking findings.
