fix(sdk): verify-package always fails when it runs — plugin-github missing from the pack list #159

Summary

The Linux-only Verify packed workerd SDK step in test.yml fails whenever it actually runs: packages/sdk/script/verify-package.ts throws @opencode/core has unpacked workspace dependencies: @opencode/plugin-github. It usually goes unnoticed because the step runs bun turbo verify:package --affected --filter=@opencode/sdk, and on runs where @opencode/sdk is not affected turbo executes zero tasks and the step passes vacuously.

Evidence

• Surfaced on PR test(sdk): expect the protocol SessionNotFoundError tag from sessions.get #158 (run 39377741794, unit (linux) job 118479582962): the @opencode/sdk:test task itself passed 39/39 (including the transport tests fixed for test(sdk): transport tests fail on main at the sessions.get error assertion — sessions.get error does not match {_tag: SessionNotFoundError} in the test flow (unit linux red) #62), unit (windows) passed fully (this step is if: runner.os == 'Linux'), and the job's only failure was the later verify step:
  error: @opencode/core has unpacked workspace dependencies: @opencode/plugin-github at packages/sdk/script/verify-package.ts:46.
• verify-package.ts:11-24 hard-codes the pack order in names (schema, codemode, ai, util, protocol, client, plugin, plugin-browser, core, simulation, server, sdk) — plugin-github is not in the list, so no archive for it ever exists when core is checked.
• packages/core/package.json lists "@opencode/plugin-github": "workspace:*" under dependencies.
• Both arrived in the same commit (1fc489d878); git log -S plugin-github -- packages/sdk/script/verify-package.ts is empty — the script has never accounted for the package.

Expected fix direction

Add "plugin-github" to names before "core" (its own workspace deps, @opencode/plugin and @opencode/schema, are already packed earlier), then verify the whole step end to end: bun turbo verify:package --filter=@opencode/sdk should run the packed-consumer checks and exit 0, and a PR touching packages/sdk should show unit (linux) fully green. Check packages/plugin-github's build/pack behaviour in this flow (its exports use ./src/*.ts wildcards) as part of the verification.

Acceptance criteria

• bun turbo verify:package --filter=@opencode/sdk passes locally / in CI.
• A PR affecting @opencode/sdk shows the Verify packed workerd SDK step green (not vacuously skipped).
• No package.json files are left modified by a failed verify run.
