All 10 vector primitives now have :as type annotations on every parameter,
:returns types, and :doc strings. make-vector gains optional fill annotation;
vector uses :rest for its variadic args; vector-ref/set! document bounds error.

vector-ref and vector-set! now raise Eval_error on out-of-bounds index instead of
an OCaml array exception. vector-copy accepts optional start and end parameters for
slicing (R7RS §6.8). spec/primitives.sx doc updated to reflect slice params.

Plans + briefings for four new language loops, each with a delcc/JIT
showcase that the runtime already supports natively:
- common-lisp — conditions + restarts on delimited continuations
- apl — rank-polymorphic primitives + 6 operators on the JIT
- ruby — fibers as delcc, blocks/yield as escape continuations
- tcl — uplevel/upvar via first-class env chain, the Dodekalogue
Launcher scripts now spawn 12 windows (was 8).
Five new guest-language plans mirroring the js-on-sx / hs-loop pattern, each
with a phased roadmap (Progress log + Blockers), a self-contained agent
briefing for respawning a long-lived loop, and a shared restore-all.sh that
snapshots state across all seven language loops.
Briefings bake in the lessons from today's stall debugging: never call
sx_build (600s watchdog), only touch lib/<lang>/** + own plan file, commit
every feature, update Progress log on each commit, route shared-file
issues to Blockers rather than fixing them.

40 clusters across 6 buckets. Bucket E is human-only (WebSocket,
Tokenizer-API, SourceInfo, WebWorker, fetch non-2xx). Agent loop
works A→B→C→D→F serially, one cluster per commit, aborts on
regression.

Initial commit of the lib/js/ tree and plans/ directory. A previous
session left template-string work in progress — 278/280 unit tests pass
(2 failing: tpl part-count off-by-one, escaped-backtick ident lookup).
test262-runner.py and scoreboard are placeholders (0/8 with 7 timeouts);
fixing the runner is the next queue item.
