fed-sx-m1: 8b-bridge cleanup — remove dead helpers + duplicate test

Step 8b-bridge was actually completed in 0f85bd96 (Step 8b-start) using
er-request-dict-to-proplist / er-proplist-to-dict plus er-spawn-fun to
host the handler inside a real Erlang process. My previous commit
(31ff1e6a) shipped a parallel set of helpers (er-http-req-of-sx,
er-http-resp-to-sx and friends) plus a duplicate test under
next/tests/http_listen_bridge.sh — the BIF body never referenced them,
so they sat in runtime.sx as dead code while http_marshal.sh already
covered the live marshalers.

This commit:
  - deletes the 8 dead helpers from lib/erlang/runtime.sx
  - deletes the duplicate next/tests/http_listen_bridge.sh
  - rewrites next/README.md substrate gap #3 to name the helpers and
    tests that are actually live

No behaviour change. Erlang conformance still 761/761; http_listen_bif
5/5, http_route 11/11, http_publish_fold 10/10, http_marshal 10/10.

-(* sx_persist_store — host durable-storage adapter for lib/persist.
-   Production twin of `persist/serve` (lib/persist/durable.sx): it answers the
-   same `persist/...` IO ops, but backs them with real on-disk storage so writes
-   survive a process restart. Stateless-on-disk: every op reads/writes the
-   filesystem directly, so a fresh process recovers state with no warm-up — the
-   log on disk IS the state.
-
-   On-disk layout under the root dir (default ./persist-data, or $SX_PERSIST_DIR):
-     streams/<hex(stream)>.log   append-only, one SX-serialized event per line
-     streams/<hex(stream)>.seq   per-stream monotonic high-water counter (int)
-     kv/<hex(key)>               one SX-serialized value per key
-
-   Invariants honoured (see plans/persist-on-sx.md Blocker spec):
-   1. last-seq is a per-stream monotonic counter stored in .seq, SEPARATE from
-      the rows — it keeps climbing across truncate, so a compacted stream never
-      reassigns a seq.
-   2. append never renumbers — the event already carries its :seq (log.sx does
-      last-seq+1); the host only bumps the high-water mark to max(hw, seq).
-   3. read returns surviving events in append order with :seq intact.
-   4. streams is the set of streams that ever had an append — keyed off the .seq
-      file, which truncate never deletes, so it survives full compaction.
-   5. values round-trip structurally via the SX serializer/parser. *)

-;; Policy — inheritance + federation with deny-overrides:
-;;
-;;   eff_grant(S,A,R) :- grant(S,A,R).                         ; direct
-;;   eff_grant(S,A,R) :- member_of(S,G), eff_grant(G,A,R).     ; group/role chain
-;;   eff_grant(S,A,R) :- child_of(R,P), eff_grant(S,A,P).      ; resource tree
-;;   eff_grant(S,A,R) :- member_of(S,Role), role_grant(Role,A,R). ; role expansion
-;;   eff_grant(S,A,R) :- delegate(Peer,S,A,R),                 ; federated grant
-;;                       trust(Peer,L), level_covers(L,A).
-;;
-;;   eff_deny(S,A,R)  :- deny(S,A,R).                          ; direct
-;;   eff_deny(S,A,R)  :- member_of(S,G), eff_deny(G,A,R).      ; group chain
-;;   eff_deny(S,A,R)  :- child_of(R,P), eff_deny(S,A,P).       ; resource tree
-;;
-;;   permit(S,A,R)    :- eff_grant(S,A,R), not eff_deny(S,A,R).
-;;
-;; DENY-OVERRIDES: an effective deny anywhere in the inheritance closure of
-;; (S,A,R) defeats any effective grant — including federated grants. Deny
-;; inherits through the *same* group and resource chains as grant, so a
-;; group-level or ancestor-resource deny is authoritative for members/
-;; descendants. This is the principled, fail-safe reading of "deny wins".
-;;
-;; FEDERATION — non-transitive trust: a peer's `delegate` fact only grants if a
-;; *local* `trust(Peer, L)` exists AND that level `level_covers` the action.
-;; Trust is re-checked on every query (it is a body literal), never baked in at
-;; fact-ingestion time, so revoking trust or narrowing a level takes effect
-;; immediately on the next decision.
-;;
-;; Termination & stratification:
-;;   - eff_grant/eff_deny recurse only over member_of and child_of, which are
-;;     EDB relations with no function symbols, so the closure is finite (cyclic
-;;     membership/containment just reaches a fixpoint, never loops). The
-;;     federation rule is non-recursive.
-;;   - permit negates eff_deny; neither eff_grant nor eff_deny depends on
-;;     permit, so the program is stratifiable (permit sits in a higher stratum).

-;; lib/acl/tests/harden.sx — adversarial / cross-phase hardening.
-;;
-;; Diamond hierarchies, conflict resolution where deny must win through every
-;; path, chain inheritance, cycle termination, multi-peer delegation, fact
-;; validation, and audit save/restore.
-;;
-;; PROVER-FREE BY DESIGN: this suite calls only acl-permit? (which runs in
-;; compiled Datalog, safe at any depth) plus pure data ops — never acl-explain /
-;; acl-prove-d. The SX-side proof reconstructor recurses, and once the kernel
-;; JIT-compiles it (after the explain/fed suites warm the process) it loops on
-;; chains deeper than ~3 (substrate JIT bug — see plan Blockers). Proof
-;; reconstruction is covered by tests/explain.sx (and federated proofs by
-;; tests/fed.sx), both of which stay under the warm-process depth threshold.
