v0.1.0

First tagged release of tt-env-go, a statically compiled Go re-implementation
of the tt-env Tenstorrent stack environment manager. It reaches feature parity
with the Bash prototype's core workflows and ships hosted CI plus reproducible,
release-stamped binaries.

Added

• CLI skeleton built on Cobra with structured logging and a --log-level
  flag.
• status command that probes the active release, installed releases,
  detected Tenstorrent hardware, and KMD/Secure Boot state.
• use, list, and remove commands for switching, enumerating,
  and uninstalling local stack releases via the active-version symlink and
  generated command shims.
• update command that refreshes release manifest catalogs.
• diff command that compares two release manifests, reporting version and
  dependency differences.
• install command that provisions a release from its manifest, including
  system packages through package-manager adapters, git component clones, and a
  pinned Python virtual environment; supports --dry-run, --force, and
  --latest (unpinned/HEAD) installation modes.
• capture command that produces a local-only stack release manifest by
  probing installed package, pip, and git component versions, with --from to
  decouple the probed tree from the base manifest template, and GHCR digest
  resolution to pin container components to their latest image digests.
• version subcommand and --version flag reporting the build version,
  git commit, and build date embedded at link time.
• Continuous integration running gofmt, go vet, golangci-lint,
  govulncheck, a multi-version go test -race matrix, and cross-compiled
  linux/amd64 and linux/arm64 builds.
• Release automation that builds version-stamped static binaries for
  linux/amd64 and linux/arm64 with checksums and publishes them to a GitHub
  Release on v* tags.
