v2.1.2: bump opencode 1.17.6->1.17.7

Image-semver patch: opencode-only version bump (variant-layer rebuild).
Upstream 1.17.7 is bugfixes + minor improvements, no breaking/runtime/Bun/AVX
changes. Also fixes a stale CHANGELOG preamble that still described the
pre-v2.0.0 'v{opencode_version}[letter]' scheme instead of independent semver.

 All notable changes to the opencode-devbox container image.
 
-Tags follow `v{opencode_version}[letter]` — bare tag for the first build on a new opencode release, letter suffix (`b`, `c`, …) for container-level rebuilds on the same version. See [AGENTS.md](AGENTS.md#versioning-scheme) for details.
+Tags follow **independent semver** (since `v2.0.0`) — they version *this image*, not the bundled opencode release. MAJOR = breaking run/config changes, MINOR = backward-compatible features, PATCH = opencode/tool version bumps and small fixes. Pre-`v2.0.0` tags used the older `v{opencode_version}[letter]` scheme. See [AGENTS.md](AGENTS.md#versioning-scheme) for details.

+Image-semver **patch**: bumps opencode to `1.17.7`. No devbox-side changes
+beyond the `OPENCODE_VERSION` ARG, so only the variant layer is rebuilt; the
+base is unaffected by this change.

+### Bumped: opencode-ai 1.17.6 → 1.17.7
+
+`OPENCODE_VERSION` ARG in `Dockerfile.variant`. Upstream `1.17.7` (published
+2026-06-14) is a bugfix-and-minor-improvement patch with no breaking,
+runtime-dependency, bundled-Bun, or CPU/AVX changes — a pure version bump on
+the devbox side. Upstream highlights:
+
+- **Core (bugfixes):** plugin client requests now reuse the active server
+  instead of assuming the default local port; ACP shell tool calls show the
+  command and working directory from the start; plugin-provided shell
+  environment variables now apply to PTY sessions.
+- **Core (improvements):** MCP servers can now receive the current workspace as
+  a client root.
+- **TUI:** MCP debug now uses the SDK's latest protocol version.
+- **Desktop:** the new-session route stays scoped to its own draft server, so
+  prompts and state target the right workspace.
+- **SDK:** clients refresh model and provider availability when integrations
+  change; credential update and remove calls accept `location`.
