📄 docs: bring the landing page up to 0.4.0

The page still described 0.3.0. Two of the stale strings were in a shell
block a visitor is meant to copy — `npm pack # → cereale-0.3.0.tgz` then
`npm install ../cereale/cereale-0.3.0.tgz`, which is an ENOENT for anyone
following the install instructions today.

Corrected: five version strings (the badge fallback, the pack/install pair,
the "lives in the repository" claim, and the diagnosability paragraph, which
becomes past tense rather than 0.4.0); seven GitHub URLs using the
redirect-only capitalised org name, which the framework table added in 0.4.0
had already stopped doing; NestJS pinned to 11.1 and Bun to 1.3, matching
FRAMEWORKS.md, where every other row was already pinned; `tsc` given its 5.2
floor, which the page had never stated anywhere.

Added, all of it absent before:

- A bundle-size section with the measured table across esbuild, rollup and
  webpack, the independence of the serializer and deserializer, and why the
  regression was invisible to a single-bundler measurement.
- `cereale/min` in the install section, with the import-map form and the
  caveat that leads FRAMEWORKS.md — if you have a bundler, do not use it.
- Hero: a third shipped format, and the size fact that the 68-decorator chip
  invites.
- The verification date on the framework claim; "the three ✓ rows" made
  unambiguous now that the section has a second table.

Every figure is quoted from CHANGELOG.md or FRAMEWORKS.md rather than
recalled. check:docs passes, the generated files stay in sync, and the markup
parses with no unclosed or mismatched tags.
