fix(opencode.ai): improve install robustness and test coverage

[Copilot]

The opencode.ai feature has had recurring install failures traced to accumulated technical debt: a non-standard debian_get_arch() implementation with an unscoped arch variable, missing apt_get_cleanup at the end of install(), and a test that only checks file existence rather than binary execution.

Changes

• install.sh: Add local arch in debian_get_arch() to prevent variable leak under set -o allexport; remove stale commented-out dpkg line; add apt_get_cleanup call at end of install() to match the standard pattern used by fzf, starship.rs, and others
• test/opencode.ai/test.sh: Replace existence-only check with opencode --version to catch runtime failures (missing libs, wrong binary, broken extraction)
• devcontainer-feature.json / root README.md: Version bump 1.0.6 → 1.0.7

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Implement the suggested changes

Done in d896f45. Applied all three changes:

1. install.sh — debian_get_arch() now uses local arch (prevents leak under set -o allexport), removed the stale commented-out dpkg line, fixed indentation; added apt_get_cleanup at the end of install()
2. test.sh — replaced the file-existence check with opencode --version to verify the binary actually runs
3. Version — bumped 1.0.6 → 1.0.7 in both devcontainer-feature.json and root README.md
