fix(ci): --no-worktree on release-smoke archon-assist invocations

[Wirasm]

Summary

v0.3.8's release CI failed deterministically on this step:

Smoke-test Claude binary-path resolver (negative case) — expected "Claude Code not found" in output; got "Failed to fetch base branch from origin: Cannot detect default branch ... neither origin/HEAD nor origin/main exist" instead.

The test creates a fresh git init tempdir with no origin remote and runs archon workflow run archon-assist "hello". As of #1310's worktree-policy changes, default isolation auto-syncs the worktree with origin before creation; with no origin, that sync fails — before the Claude resolver is even reached — so the assertion never matches and the whole linux-x64 build aborts (fail-fast kills the other matrix entries).

Change

Add --no-worktree to both invocations (negative + positive cases). The tests exercise the Claude resolver / subprocess-spawn path, not worktree setup, so skipping isolation is the right answer. This short-circuits validateAndResolveIsolation and never touches origin. Matches the documented usage pattern in CLAUDE.md:

archon workflow run quick-fix --no-worktree "Fix typo"

Not this PR

• Binaries themselves are fine. The v0.3.7 Pi-lazy-load regression (fix(providers/pi): lazy-load Pi SDK to unbreak compiled archon binary #1355) is fixed on dev; local bun build --compile --minify produces a working binary; the repo's new Step 1.5 pre-flight smoke passes with --help. The only thing broken was the CI assertion, not what it asserts against.
• Not reusing the v0.3.8 tag. v0.3.8's GitHub Release has been deleted (releases/latest falls back to v0.3.6); next release will be v0.3.9 with this fix applied.

Test plan

• CI green on bun run validate (no source changes, should be trivial)
• v0.3.9 release workflow gets past both resolver smoke tests

📝 Walkthrough

Walkthrough

The GitHub Actions release workflow has been updated to add the --no-worktree flag to both smoke-test invocations of the archon-assist workflow run. The negative case test modified to include this flag with unset CLAUDE_BIN_PATH, and the positive case test also now includes this flag with CLAUDE_BIN_PATH explicitly set.

Changes

Cohort / File(s)	Summary
Release Workflow Smoke Tests .github/workflows/release.yml	Added --no-worktree flag to both "Smoke-test Claude binary-path resolver (negative case)" and "Smoke-test Claude subprocess spawn (positive case)" archon-assist workflow run invocations.

Poem

🐰 A flag so small, yet oh so fine,
--no-worktree makes tests align,
With whiskers twitched and tests pristine,
The cleanest workflow ever seen!
Hop along to release day! 🚀
