perf: shrink the published package

[hyamero]

Unpacked package size goes from 1.61 MB to 825 KB. The tarball is 318 KB.

file	before	after
dist/cli.js	918 KB	173 KB
dist/viewer.html	644 KB	622 KB

• zod tree-shaking: import { z } from 'zod' pulled in the whole namespace, including 358 KB of error messages in every language. import * as z lets the bundler drop them. The CLI is also minified now.
• Kerning table: stored as a compact string instead of an object literal, 119 KB down to 49 KB. The tabular-digits face is stored as the weight-500 face minus its 212 digit pairs. The decoded table matches the old one pair for pair; I checked every face. The generator writes through the same encoder.
• Brand icons: brands.gen.ts keeps only title and path for each allowlisted mark, dropping colour, source URLs and licence fields. The table is regenerated with bun run icons:gen, and a test fails if it drifts from simple-icons.

All unit tests, typecheck, viewer and CLI e2e, and the smoke test pass locally.
