Yogthos 33eff7c7d8 Clean up codebase: rename stdlib layer, strip porting residue, fix tooling
Rename src/jolt -> stdlib (the runtime-loaded layer; jolt-core stays the
seed-baked layer) and update the loader / emit-image / doc paths. Drop dead
code: the spike/ experiments, the duplicate clojuredocs-export.edn (json moves
to tools/), the Janet-era jolt.http binding, and the orphaned
persistent_vector.clj whose ns/path didn't even match.

Strip porting residue from comments and docstrings across host/chez, jolt-core,
stdlib, tests, and docs: internal issue ids, "Phase N" markers, and the "vs
Janet" historical exposition, leaving present-tense descriptions and the real
JVM-Clojure semantic contrasts. Same pass over the corpus suite labels. The seed
is unchanged (docstrings/comments aren't emitted), so the self-host fixpoint and
corpus are untouched.

Port tools/spec_coverage.py off the dead janet probe to bin/joltc and regenerate
coverage.md; drop the dead :host/janet rule from certify.clj and regenerate the
conformance profile. Add docs/host-interop.md (the JVM shims and how to register
your own host class from a library) and a writing-style note in CLAUDE.md.

Stabilize the four racy concurrency corpus cases (future-cancel and agent
send/send-off): give the future a sleeping body and the agent a slow action, so
cancel reliably catches an in-flight future and deref reliably reads the
pre-update snapshot. They certify deterministically now, so drop their :flaky
allowlist entries and the orphaned legend.

;; Collection constructors + rand — host-coupled natives the overlay assumes as
;; bare clojure.core vars. The persistent-collection constructors already exist
;; in collections.ss (jolt-hash-map / jolt-hash-set / jolt-vector); this just
;; binds the public clojure.core names to them. Loaded after def-var! (rt.ss) +
;; the collections + seq tiers. hash-map/array-map/hash-set/set/rand semantics.
;; hash-map / hash-set: variadic kvs / elems straight onto the existing ctors.
;; array-map: Clojure preserves insertion order, but jolt's `=` is structural and
;; the parity corpus compares by value, so a pmap is observationally equal for
;; the tested cases; keys-ordering is a separate (untested-here) concern.
