dimgigov eb81856565 feat: HTTP registry, app/bench harnesses, and DWARF #line maps

Ship QUALITY_PLAN sessions 31–33: fetchable package index URLs, showcase
app and micro/nexus benchmarks, and debugger-friendly C codegen.

- Registry: BUX_REGISTRY accepts http(s) URLs (curl/wget → ~/.bux/cache)
- E.2: make test-apps smoke for nexus/boko/simpledb/jwt-pitbul
- E.5: benches/micro + C/Nim/Zig twins; make bench-nexus (wrk)
- E.4: HIR locs → #line .bux; default -O0 -g; --release -O2; make test-dwarf

Bux benchmarks (E.5)

Micro-kernels + optional Nexus HTTP throughput for regression and language comparison.

Quick run

# From repo root
make bench              # Bux micro + C + Nim (+ Zig if installed)
make bench-nexus        # wrk vs apps/nexus /api/health
BENCH_NEXUS=1 make bench

Micro suites

Suite	Kernels	Build
`micro/`	Bux: `int_loop`, `fib30`, `string_concat`, `array_push`	`buxc build`
`c/`	C: `fib30`, `int_loop`	`gcc -O2`
`nim/`	Nim twins	`nim c -d:release --opt:speed`
`zig/`	Zig twins (optional)	`zig build-exe -OReleaseFast`

Output lines:

BENCH <name> iters=N total_us=T us_per_op=P

Nexus throughput

tools/bench_nexus.sh / make bench-nexus:

Builds apps/nexus
Starts on NEXUS_PORT (default 18080), bind 127.0.0.1
wrk -t4 -c64 -d5s against /api/health
Prints BENCH nexus_health rps=…

Env knobs:

Variable	Default	Meaning
`NEXUS_PORT`	`18080`	Listen port (also used by the server binary)
`NEXUS_WORKERS`	`4`	Worker threads
`NEXUS_BENCH_DURATION`	`5s`	wrk `-d`
`NEXUS_BENCH_C`	`64`	wrk connections
`NEXUS_BENCH_T`	`4`	wrk threads

Server-side (any nexus run):

NEXUS_PORT, NEXUS_WORKERS, NEXUS_BIND, NEXUS_PUBLIC

Notes

Numbers vary by machine; use them relatively (same host, same day).
Nexus currently closes connections (Connection: close) — RPS is honest for that model, not keep-alive maxed.
Requires wrk for bench-nexus (apt install wrk on Debian/Ubuntu).
