v2.24.0

Added

• New simplifier team agent (agents/simplifier.md). De-over-engineers code
  that already works and breaks no hard rule but carries more complexity than its
  problem requires — premature abstraction, needless indirection, speculative
  generality, premature optimization, and drifted duplication. Distinct trigger from
  refactorer: refactorer fixes hard-rule violations; simplifier removes
  superfluous complexity that violates no hard rule (already-functional,
  already-compliant code never invokes refactorer, so over-engineering needs its own
  trigger — folding both into one agent would be an SRP violation in agent design).
  Behavior-preserving (tests pass before and after, one simplification per commit),
  stakes-calibrated, and language-/project-agnostic (idiom-mapping across Python,
  TypeScript, Go, Rust, Java, Swift). Its over-engineering heuristics are an open,
  non-exhaustive catalog (YAGNI, rule-of-three, needless indirection, premature
  optimization, speculative generality, drifted duplication, plus KISS, Gall's Law,
  Ousterhout shallow modules, dead code, boolean blindness, …) — each removal must
  name and source its principle per the zetetic §8 standard. New simplifier memory
  scope (memory/scope-registry.json).
• A2 / CR-4 — adversarial-verify pre-verdict workflow now carries a fifth,
  perspective-diverse lens: simplicity (agentType simplifier), prompted to
  REFUTE by hunting superfluous complexity that no hard rule forbids. Joins the four
  existing refute lenses (residual-fp, missed-cases, robustness, test-adequacy);
  synthesis stays deterministic and fail-closed. (The A2/adversarial-verify work
  shipped in code prior to this release without a CHANGELOG entry; recorded here.)

Changed

• code-reviewer Move 5 now hands off superfluous-complexity smells (over-
  engineering with no hard-rule violation) to simplifier as an advisory note,
  distinct from the §4 size-breach blocking gate. Output format and blind-spot
  hand-off list updated accordingly.
• README badge, body, CONTRIBUTING.md, and the marketplace plugin/metadata
  descriptions refreshed: 97 reasoning patterns + 21 team agents (118 total).
  rules/agent-routing-table.md regenerated (118 agents).
• memory/scope-coverage.md: simplifier added to the team table; counts reconciled
  to 20 scope-owning team agents, 117 tabulated agents, 27 distinct registry
  scopes (7 systemic + 18 team + 1 research + 1 genius). This doc tabulates only
  scope-owning agents, so its total is intentionally one less than the 118 agent
  definition files the README/marketplace count — memory-writer is a scribe that
  owns no scope. A new footnote in the doc records the distinction.

Tests

• tools/tests/adversarial-verify/core.test.mjs updated for the five-lens core
  (lens count, lens-keys ordering, distinct-agentType count, five-element fixtures).
  13/13 deterministic synthesis-core tests pass.
