test(elixir): CRG D→C — expand test suite to 165 tests (10 properties + 155 regular)

Adds 7 new test files and extends all 5 existing test files to cross the
CRG C threshold of 165 tests. Every test passes with 0 failures.

New files:
- invoker_test.exs (15 tests) — exit-code classification via fake_boj_invoke fixture
- js_worker_pool_test.exs (9 tests) — pool size, consistent-hash routing, fallback
- catalog_properties_test.exs (10 StreamData properties) — round-trips, CredentialDecryptor
- contract_test.exs (15 tests) — Catalog↔Router, NodeKey↔CredentialDecryptor, dispatch
- aspect_test.exs (15 tests) — no-crash, content-type, security, idempotency
- benchmarks/boj_bench.exs (10 Benchee scenarios) — Catalog, NodeKey, Router, ECDH
- test/fixtures/fake_boj_invoke — shell script for exit-code classification tests

Extended existing files: +80 tests across catalog, router, credential_decryptor,
node_key, js_invoker (HTTP method rejection, schema completeness, ECDH round-trips,
idempotency, StreamData property generators).

Also fixes cartridge metadata in bofig-mcp, hesiod-mcp, academic-workflow-mcp
(added missing spdx, copyright, domain, tier, auth, ffi.so_path fields) and
updates TEST-NEEDS.md + STATE.a2ml to reflect grade D→C.

-## Path to CRG Grade C
-
-### P1 — Expand unit tests to 100+ (Gap: 50 tests)
-
-Priority areas:
-- `BojRest.Catalog`: edge cases — malformed JSON in cartridge.json, empty tools list,
-  cartridges_root not found, duplicate detection
-- `BojRest.Invoker`: all exit code classifications (args/open/symbol/init/crashed),
-  `cli_path/0` resolution order, `probe/1`, `name/1`, `version/1`
-- `BojRest.JsInvoker`: runner_path resolution, bad JSON output, timeout path
-  (requires a slow mod.js fixture), application-level error (4xx/5xx status codes)
-- `BojRest.CredentialDecryptor`: ciphertext too short, JSON-in-plaintext-has-int-values
-- `BojRest.NodeKey`: key file persistence (tempdir), env var loading paths
-- Router: `POST /invoke` with encrypted credentials end-to-end
-
-### P2 — Property tests to 15+ (StreamData installed, Gap: 4+ tests)
-
-`stream_data ~> 1.1` is in `mix.exs` (only: test).  Write StreamData property tests in:
-- `catalog_test.exs`: for all cartridges, `get(cart["name"])` always returns the cart back
-- `credential_decryptor_test.exs`: any string→string map plaintext from loopback always
-  passes; any non-string value always fails validation
-- `router_test.exs`: GET /cartridge/<any name from list> always returns 200
-
-### P3 — Contract tests (Gap: 13)
-
-Use `ExUnit` contract-style modules (or add `pact_elixir` when available):
-- One module per boundary: Catalog↔Router, JsInvoker↔Runner, Router↔Invoker,
-  NodeKey↔CredentialDecryptor, CredentialDecryptor↔Router
-
-### P4 — Aspect tests (Gap: 14)
-
-Panic-free aspects from `panic-free-tests-and-benches` Clade A standard:
-- No process crash on any valid input (Clade A goal)
-- `BojRest.Catalog.get/1` never throws
-- Router always returns valid JSON content-type
-- CredentialDecryptor never leaks key material in error strings
-- NodeKey survives concurrent reads under `Task.async_stream`
-
-### P5 — Benchmarks (Gap: 10)
+## Path to CRG Grade B
 
-Add `benchee ~> 1.3` (only: dev):
-- Catalog `list/0` with 107 cartridges (ETS read)
-- Catalog `get/1` hit vs miss
-- CredentialDecryptor: plaintext vs encrypted path
-- NodeKey ECDH round-trip
-- JsInvoker cold-start time (requires Deno)
+Grade B requires:
+- External validation targets (published test results, CI badge)
+- Mutation testing (Muzak or equivalent) showing >80% mutation kill rate
+- Six Sigma benchmark targets (latency at 99th percentile)
+- Security/fuzz corpus for CredentialDecryptor
