docs(tasks): decompose review-002 into 24 tasks (23 implementation + 1 bracketed follow-up)

Decomposition of docs/reviews/002-post-remediation-review.md per its
5-unit remediation plan:

- Unit 1 (security-critical): gw15-publish-body-cap,
  prj16-schema-via-call (CF-004 filed alkcall-side), fwd13-dot-segments,
  fwd16-missing-capability, oai11-ref-memoization
- Unit 2 (timeout/terminality): ws13-idle-progress,
  fwd15-stream-timeout, cli01-retry-after-budget, con17-mcp-pagination,
  con18-wss-sweep-exit
- Unit 3 (projection/docs): projection-truthfulness, mcp-batch-cap,
  gw16-status-drift
- Unit 4 (spec-import): yaml-normalization, oai13-path-item-wildcards,
  import-loudness-cluster, js01-placeholder-check,
  fwd17-19-contract-decisions
- Unit 5 (WS polish + tests): con18b-ws-polish,
  client-policy-wire-tests, cov-deployment-knobs, cov13-dead-code,
  srv11-srv12-router-ordering
- review-002-bracketed-followup: tentatively planned post-bulk pass
  (stale-check, OQA-18 enforcement decision, CON-08/09 close() lever,
  cross-crate re-checks) — deliberately not serialized against the
  bulk

Also: review-002 numbering repair (CON-14 was double-booked; MCP
pagination now CON-14, from_wss monitor renumbered CON-18, missing
CON-14 section added).

taskgraph: 66 valid, no cycles; 24 pending (all review-002);
gen-1/gen-2 parallel waves identified; workflow-cost hotspots are
prj16 (12.8) and ws13 (11.1), both carrying the reviewed slicing
guidance in their Notes.

+name: Import loudness cluster — oneOf body, self-ref requestBody, siblings, collisions, header precedence, error truncation (OAI-10/14/15/17/19, JS-02/03)

+## Description
+
+Six review-002 minor findings across the two import files, all in the
+"unsupported-feature loudness + import robustness" family (the OAI-06
+matrix completion). Batched — each is small:
+
+- **OAI-10**: `$ref` sibling keys are silently discarded
+  (openapi_spec.rs:396-410). Under 3.1 semantics siblings apply
+  alongside the `$ref` (advertise/enforce drift); there is no
+  `openapi: 3.1` version gate anywhere. Fix: warn on `$ref` siblings,
+  and/or gate `openapi: "3.1*"` like other unsupported features
+  (at minimum document the 3.0-only stance).
+- **OAI-14**: top-level `oneOf` requestBodies (unconstraining `body`
+  contract — import-time gate), `discriminator`, `xml`, `callbacks`,
+  `security` blocks silently ignored. Extend the OAI-06 loudness
+  matrix: reject-or-warn at import with the established message
+  template.
+- **OAI-15**: a self-`$ref`'d requestBody resolves to content-less →
+  body-less op registered silently (openapi_spec.rs:486-498). Fail
+  import with the OAI-04 error shape when a resolved requestBody
+  still contains a top-level `$ref` or lacks `content`.
+- **OAI-17**: import errors echo unbounded spec-derived strings
+  (openapi_spec.rs:264-272 servers locations join; from_openapi.rs
+  placeholder/path interpolation). Truncate (first N + count) and cap
+  interpolated path/ref strings in `SchemaParse` messages.
+- **OAI-19**: declared `in: header` params silently lose to
+  `default_headers` and credential headers (forward.rs:169-238 insert
+  order). Reject or warn at import when a header param collides with
+  a configured `default_headers` key or the auth scheme's header;
+  also reject peer-visible header params named `Authorization` on
+  authed namespaces.
+- **JS-02**: `from_openapi` templates are not validated for balanced
+  braces at import (`/x{open` imports, fails per-call INTERNAL) —
+  reuse/hoist `from_jsonschema`'s `validate_path_template` into the
+  shared path and run it in `build_registration`.
+- **JS-03**: `assert_eq!` in library code (`reject_collisions`,
+  from_openapi.rs:74-75) — return `Err(AdapterError::internal(…))` or
+  zip-iterate and drop the asserts.
+
+## Acceptance Criteria
+
+- [ ] Each item landed with its import-time test (loud-error content
+      asserted; sibling-warning case; header-collision warning/reject;
+      unterminated-template import failure; no asserts in non-test code)
+- [ ] OAI-17: a 100k-path servers-list import error message is
+      bounded (test with a large synthetic spec asserting message
+      length < a sane cap)
+- [ ] The OAI-06 matrix (or its successor doc section) lists the newly
+      loud features
+- [ ] `cargo test`, `cargo clippy --all-targets -- -D warnings`,
+      `cargo fmt --check` pass

+## Notes
+
+Sequence after review-002-oai11-ref-memoization (same resolver
+function for OAI-10/15 — or rebase-verify). Slice per finding, commit
+per finding. The OAI-19 import-time check may not see the assembly
+layer's `default_headers` (config lives elsewhere) — if the
+import-time surface cannot know, the loud point moves to
+first-call-time (warn-once) — implementer documents which.
