Brings the loops/erlang stdlib hardening into the canonical files so
every erlang consumer (fed-sx, identity, ...) gets them — not just a
separate conformance-only file.
lists: sort/1,2 usort/1 keyfind/keymember/keydelete/keyreplace/keystore/
keytake/keysort foldr partition takewhile dropwhile splitwith flatten
max min zip zipwith unzip sublist/2,3 nthtail split droplast flatmap
filtermap mapfoldl search.
proplists: get_value/2,3 get_all_values is_defined lookup delete.
Impls appended to transpile.sx; registrations added directly inside
er-register-builtin-bifs! (so they survive the registry resets that
tests/runtime.sx performs — no wrapper needed when folded in). Full
term order via self-contained er-ext-lt? (the shared er-lt? does not
deep-compare tuples/lists). New lists_ext suite wired into
conformance.conf (dict mode). Conformance 771 -> 874/874.

Logical-clock timer wheel in the scheduler. send_after schedules a
message-delivery event at an absolute deadline (clock + Time ms);
cancel_timer marks a live timer cancelled and reports remaining ms,
or false. Time advances only when the runnable queue drains, jumping
to the earliest pending deadline (deterministic, no wall clock).
monotonic_time/0,1 exposes the logical ms clock.

er-eval-binary-segment evaluated a string-valued segment (the parser
represents <<"abc">> as one integer segment whose value is the whole string
"abc") by calling er-emit-int! on the string, emitting a single bogus 0
byte. So every <<"...">> literal became {:tag "binary" :bytes (0)} — which
made binary =:= read as "always equal" and crypto:hash input-independent.
Fix: the integer branch now expands a string value to one byte per
character (Erlang semantics: <<"abc">> ≡ <<97,98,99>>). Verified:
byte_size(<<"abc">>)=3, <<"a">> =:= <<"b">> is false, crypto:hash distinct
per input.
(User-authorized cross-scope fix from the identity loop; loops/erlang
should adopt this as the owner of lib/erlang.)
