Remove gettext-base/envsubst dependency from astral.sh-uv, opencode.ai, atuin.sh, and btop

[Copilot]

gettext-base is unavailable on some minimal base images, causing envsubst-dependent features to fail at install time. btop was additionally broken by a renamed release asset.

Changes

Drop envsubst / gettext-base across four features

Replace the template-variable pattern with direct bash expansion:

# Before
readonly downloadUrlTemplate='https://github.com/${githubRepository}/releases/download/${version}/...'
readonly downloadUrl="$(echo -n "$downloadUrlTemplate" | envsubst)"

# After
readonly downloadUrl="https://github.com/${githubRepository}/releases/download/${releaseTag}/..."

• All four features: remove *Template variable declarations, eliminate envsubst/gettext-base from prerequisite checks, rename check_curl_envsubst_* → check_curl_*
• astral.sh-uv, opencode.ai, atuin.sh, btop: add github_get_tag_for_version helper to resolve the actual release tag (handles optional v prefix), use ${releaseTag} directly in the download URL

btop URL fix

Release assets changed from btop-<arch>-linux-musl.tbz → btop-<arch>-unknown-linux-musl.tbz; URL updated accordingly.

opencode.ai repo rename

GitHub repository updated from sst/opencode → anomalyco/opencode.

Version bumps

astral.sh-uv → 1.0.3 · atuin.sh → 1.0.2 · btop → 1.0.2 · opencode.ai → 1.0.3

@copilot tests are failing (btop, opencode, atuin)

Fixed in commit ac4900e.

• atuin: Removed the gettext-base/envsubst dependency (same fix applied earlier to astral.sh-uv and opencode.ai) — URLs are now built directly using bash variable expansion.
• btop: Removed the gettext-base/envsubst dependency, and also fixed the download URL format — btop's release assets changed from btop-x86_64-linux-musl.tbz to btop-x86_64-unknown-linux-musl.tbz, which was causing the 404 errors.
• opencode: Was already fixed in the previous commit (28f2914).

Merge conflicts. If in doubt, further increase patch version in devcontainer-feature.json files.

Tests fail for:

  ...

Fixed in commit 98ad2a0. Synced asdf-vm.com with the main branch changes from PRs #80–#83: the install script now supports binary installation for asdf ≥0.16.0, uses the /releases/latest API endpoint, and the version is bumped to 1.0.2 to resolve the merge conflict.

Resolve merge conflicts, @copilot !

Resolve merge conflicts, @copilot !

Resolved in commit 6a549f9. The branch now incorporates all of main's concurrent changes (PRs #81–#83) and resolves the conflicts by:

• Incorporating github_get_tag_for_version from main and using ${releaseTag} directly in URLs (no envsubst)
• Updating opencode.ai repo to anomalyco/opencode
• Bumping versions above both branch and main: astral.sh-uv → 1.0.2, atuin.sh → 1.0.2, btop → 1.0.2, opencode.ai → 1.0.3
