Nest 4/4: hello-nest in the HTTP benchmark matrix

[puskuruk]

Adds nest-gea and nest-node rows to bench/http-matrix.py and the Nest build to bench/goal-http-build.sh, aligns apps/hello-nest with the other benchmark apps (gea binary in dist/, tsc oracle in dist-node/, a cluster.node.mjs), and records the 2026-10-19 runs with a BENCHMARKS.md section.

• 63e7117 Add hello-nest to the HTTP benchmark matrix as nest-gea and nest-node
• 600453d Record the hello-nest Node against compiled run of 2026-10-19 on an arm64 Linux VM
• 32378b1 Record the full HTTP matrix of 2026-10-19 on the arm64 Linux VM

The Node row runs the tsc output of the same server.ts (Node's type stripping has no decorators). Measured in an arm64 Ubuntu 24.04 container (clang 18.1.3, Node 24.20.0, wrk 4.1.0) on an 8-vCPU Colima VM on an Apple M1, VM otherwise idle, house protocol. Not the bench host: the same binaries moved 25-46% between two runs an hour apart, so orders are firm and gap sizes are not. One run aborted at cpp-drogon (one worker, 63 wrk timeouts in warmup); the four controls were re-measured in a clean second run 19 minutes later.
