* chore(deps): pin opencode CLI and SDK to v1.4.9
- Bump constants.json opencodeVersion v1.2.27 -> v1.4.9 (CI source of
truth consumed by ci-tests, build-desktop, alpha/prerelease/release
workflows, and opencode-agents).
- Bump @opencode-ai/sdk across app, story-book, orchestrator,
opencode-router, server-v2, and refresh the lockfile so all workspaces
resolve to 1.4.9.
* refactor(app): adapt to @opencode-ai/sdk 1.4.9 type changes
- Move Model.reasoning reads to Model.capabilities.reasoning in
model-config.ts and model-behavior.ts (SDK flattened capabilities).
- Simplify utils/providers.ts to a pass-through; Provider now carries
source/options and Model.cost reshapes to {input, output, cache,
experimentalOver200K}, which the mapper no longer needs to translate.
- Cast session.todo() result to TodoItem[] (SDK Todo has no id).
- Update server-v2 test fixtures from 1.2.27 to 1.4.9.
Keep OpenCode version selection predictable by reading a single repo-wide constant and packaging that pin into orchestrator builds. Remove env and latest-release fallbacks so desktop, workers, snapshots, and CI stay aligned.
