chore(release): bump workspace to v1.1.0

Aligns the Cargo package version with the blueprint roadmap labels.
v1.1.0 = SDK foundation (#0) + stdlib utilities (#0.5), the first
release of the Phase 4 / v1.1 series.

Also updates docs/versioning.md:

  - Current versions table: Product 0.6.0 -> 1.1.0
  - Docker / Git tag examples: 0.2.0 -> 1.1.0

Cargo.lock regenerated by `cargo check --workspace`.
