release: v0.5.0 — ubuntu/ migration

Eight new commands across three new sub-trees (db / web / stack)
plus two cross-cutting primitives (core/version, core/docker)
landed via PR #7 (squash-merged as 955f433). Cutting v0.5.0 to
publish the migrated surface.

Highlights:

- `shimkit db <engine>` — container-first databases (mysql,
  mariadb, postgres, mongo, phpmyadmin). No host-install path.
- `shimkit web nginx vhost` — hardened vhost generator with
  opt-in SEVERE apply.
- `shimkit stack lemp` — 3-container LEMP recipe (db + php-fpm +
  nginx) with bind-mounted project root.
- `shimkit shell colors` — 256-color palette diagnostic.
- `core/version` — tool-version detection + constraint
  enforcement (5 detectors: docker, nginx, git, gpg, python).
  Wired into `docker-clean`, `db`, `stack`, and the `gpg
  git-signing` paths.
- `core/docker.DockerEnv` — shimkit chokepoint for the docker-py
  SDK; standard container/volume naming + network helpers.

Test count: 351 → 503 (+152). Gates: pytest/ruff/mypy/bandit all
green. No new optional extras (reuses [docker-clean]).

Legacy `ubuntu/` source archived at .design/archive/ and removed;
SHA-256 recorded in `.design/plans/validation-report.md`. Skipped
features documented in `.design/plans/feature-gap-analysis.md`.
