Parfii-bot f77c1b7fdc fix(v0.15.1): RED-1 CVE + typed-handoff + schema minItems
Security hotfix — v0.15.1 Wave 1 fixes from 4-parallel audit.

RED-1 (CVE): KEI_DISABLED_HOOKS tokenized match — was `*all*`
substring-glob (trivially bypassable via "install", "wall-clock", etc.),
now exact-token split on comma/space. Patched in all 9 hooks:
no-hand-edit-agents, assemble-agents, assemble-validate, tomd-preread,
agent-fork-logger, site-wysiwyd-check, error-spike-detector,
milestone-commit-hook, session-end-dump.

RED-2 (observability): minimal profile whitelist now includes
agent-fork-logger and session-end-dump (ledger + trace paths) so
observability is not silently lost on minimal installs.

HIGH: review.json schema minItems:1 on findings — rejects empty
reviews; new Rust test review_schema_rejects_empty_findings.

HIGH: typed-handoff wire-up — produces_artifact declared at top
level on 5 manifests (kei-security-auditor, kei-validator,
kei-architect, kei-code-implementer, kei-critic); duplicate
per-handoff declarations removed.

MED: kei-artifact validate.rs gains warn_unsupported_keywords —
non-fatal stderr warning when schema uses keywords outside the
hand-rolled 2020-12 subset.

LOW: CI Node matrix dropped 18, now ['20','22'].

Doc drift: skills/hooks-control/SKILL.md reflects tokenized-match
semantics and updated minimal-profile hook list.

Tests: 191 Rust workspace + 30 assembler (both pass). RED-1
reproducer 10/10 (4 former-CVE vectors blocked, 5 legit vectors
accepted, empty passes).
