Reorganize workloads into a top-level workloads/ directory

Pure cleanup/reorg; no workload changed materially.

- Move every workload under workloads/.
- Each workload gets its own subdirectory named exactly after its
  registered name, except closely-related workloads that share files
  (ARES-6, Octane, RexBench, SeaMonster, SunSpider, bigint, proxy,
  code-load, babylonjs, prismjs, transformersjs, Dart, dotnet,
  tfjs-wasm, intl, web-tooling-benchmark).
- Drop the wasm/ grouping; Wasm workloads now sit next to the JS ones.

Renamed to match workload names: wasm/HashSet -> HashSet-wasm,
wasm/TSF -> tsf-wasm, wasm/quicksort -> quicksort-wasm,
wasm/gcc-loops -> gcc-loops-wasm, wasm/richards -> richards-wasm,
wasm/argon2 -> argon2-wasm, wasm/zlib -> zlib-wasm,
wasm/j2cl-box2d -> j2cl-box2d-wasm, wasm/dotnet -> dotnet,
sqlite3 -> sqlite3-wasm, 8bitbench -> 8bitbench-wasm,
Kotlin-compose -> Kotlin-compose-wasm, mobx -> mobx-startup,
TypeScript -> typescript-lib, ARES-6/ml -> ARES-6/ML.

Split directories whose workloads shared no files: simple/,
generators/, class-fields/, worker/.

Updated path references in JetStreamDriver.js, in-depth.html,
.prettierignore, .gitignore, tests/run-license.mjs, four
webpack.config.mjs files (../utils -> ../../utils), and the
root-relative paths hardcoded inside workload sources:
transformersjs/benchmark.js (localModelPath, onnx mjs prefix),
tfjs-wasm/tfjs.js (WASM_TFJS_DIR), zlib-wasm/shell.js.
