docs(release): bump displayed version to 0.11.0 (site + install snippets) (#155)

v0.11.0 is now published across crates.io / npm / PyPI / WASM / Go, so
update the version surfaces that lag behind:

- web/src/lib/site.ts: SITE.version 0.10.0 → 0.11.0. This is the single
  source of truth the marketing site reads — it drives the hero badge,
  the docs page header, the SDK showcase cards, and the structured-data
  softwareVersion. (It was even stale at 0.10.0 through the 0.10.x line.)
- README.md / docs/embedding.md / docs/ask.md: the Rust install snippets
  pinned `sqlrite-engine = "0.1"` / `sqlrite-ask = "0.1"`. In Cargo
  `"0.1"` means >=0.1.0,<0.2.0, which EXCLUDES 0.11.0 — so copy-pasting
  resolved an ancient 0.1.x. Bump to "0.11" so the documented pin
  actually installs the current release.
