docs: add a reproducible bundle-size benchmark - #86

Conversation
tools/bench/run.mjs installs Angular and the latest openapi-resource-gen, Orval, ng-openapi-gen and Hey API into a throwaway workspace, generates a client from the 76-endpoint YouTube spec with each, builds minimal production apps that use 1 or 8 endpoints, and prints main.js sizes (raw and gzip) next to two controls (plain HttpClient, bare httpResource). Findings are in docs/benchmarks/bundle-size.md, including the unflattering one: the default httpResource flavour is not the smallest, because Angular's own httpResource runtime is most of the cost; the httpClient flavour is on par with Orval.

Roadmap #5 deliverable 3.
npm run bench(tools/bench/run.mjs) builds minimal Angular 22 production apps using 1 or 8 endpoints of the YouTube spec with each tool and prints sizes; results and caveats are indocs/benchmarks/bundle-size.md.Headline (gzip, 8 endpoints, vs plain HttpClient): ours httpResource +7.2 kB (of which +6.1 is Angular's own
httpResource), ours httpClient +1.0, Orval +1.2, ng-openapi-gen +2.3 with deep imports (+7.0 via its barrel, which doesn't tree-shake), Hey API +3.5. So the one-file-per-endpoint design tree-shakes cleanly, but we are not smallest in the default flavour; the doc says so.The README gets a one-paragraph summary and link. Not run in CI (needs network and installs five tools).
