Scrub dangling Janet references; drop dead Janet-coupled files

Browse source 
Rephrase comments that pointed at deleted Janet files (emit.janet, the seed
sources, 'the Janet back end punts ...') to present-tense descriptions of the
Chez behavior. Comment/docstring-only; the self-host fixpoint is unchanged
(comments don't affect the compiled seed).

Delete five files that were Janet-host shims with no Chez path: clojure.java.io
(provided natively by host/chez/io.ss), and jolt.{nrepl,png,interop,shell}
(the janet.* bridge, os/shell, janet.net — none exist on Chez).

@ -12,28 +12,14 @@ Both are **generated**, not hand-written. They are checked in because a fresh
checkout must be able to build jolt-on-Chez using only Chez: `host/chez/bootstrap.ss`
loads this seed, then rebuilds the prelude + image from the `.clj`/`.ss` sources via
the on-Chez compiler (read → analyze → emit, all on Chez). The seed is a **joint
byte-fixpoint**: rebuilding from an up-to-date seed reproduces it exactly
(`test/chez/bootstrap-test.janet` verifies this).
Janet was used once, historically, to mint the very first seed (the Janet analyzer/
emitter cross-compiled the sources, then the on-Chez compiler iterated to the
fixpoint — see `test/chez/fixpoint-test.janet`). After that, Janet is never needed
to build or run jolt-on-Chez.
byte-fixpoint**: rebuilding from an up-to-date seed reproduces it exactly.
`make selfhost` (`host/chez/selfcheck.sh`) runs `host/chez/bootstrap.ss` and diffs
the rebuilt artifacts against the checked-in seed.
## Re-minting
When the seed sources change (the core tiers, the compiler namespaces, the host
contract, the reader, `emit-image.ss`), the seed drifts and `bootstrap-test`
fails. Re-mint it:
```janet
(import host/chez/driver :as d)
(import host/chez/jolt-chez :as jc)
(def ctx (d/make-ctx))
(d/mint-chez-seed* (jc/ensure-prelude ctx)
(d/ensure-compiler-image ctx "/tmp/stage1.ss")
"host/chez/seed/prelude.ss"
"host/chez/seed/image.ss")
```
Then commit the refreshed `prelude.ss` / `image.ss`.
contract, the reader, `emit-image.ss`), the seed drifts and `make selfhost`
fails. Re-mint it by running `host/chez/bootstrap.ss` and writing the freshly
rebuilt prelude/image back to `host/chez/seed/prelude.ss` /
`host/chez/seed/image.ss`, then commit the refreshed files.
