Increase contrast for comments and metadata.
#928374 has about 4.0:1 contrast on the dark background and 3.3:1 on the light background. Comments and metadata are difficult to read.

Add the reviewed Go language definition, Gruvbox Dark and Light themes, and dynamic README banner while preserving the original contributor commits. Refresh Go's older language counts and bundle figures against the current core, and include a minor changeset.
Core, existing selective language bundles, adapters, and the theme helper retain no new runtime code. Go adds 373 gzip bytes to the all-language bundle on Node 24.15.0, from 8,290 to 8,663 bytes. Only the all-language budget increases. All 334 existing fixture results remain byte-for-byte identical, and paired benchmarks show no material highlighting slowdown.
Validation: full
pnpm run verifypasses, including 92 tests, package imports, tree shaking, documentation, bundle budgets, and throughput checks. Both README image URLs return valid PNGs.Integrates #10, #11, and #4 with their original authors and commits.
