Full-pool red on main: examples-contract routed-CLI count (17 vs 18) and hooks wrapper exit 1

[ScriptedAlchemy]

Triage from the #122/#200 flake-roots wave: two integration failures reproduce identically on unmodified origin/main (clean worktree, direct runs, load ~40-60), so they come from concurrently landed sibling waves, not the flake fixes (#329, #330, #332).

1. packages/agent-bundle/tests/examples-contract.test.ts :: serves the routed Audiobook Curator artifact through a real MCP client — expected [...] to have a length of 17 but got 18 (generatedRoutes assertion, line ~308). Deterministic across retry attempts; likely the audiobook example gained a route/command (e.g. the stage 3b evidence-facing CLI commands wave) without the contract expectation moving.
2. packages/agent-bundle/tests/hooks.test.ts :: runs the Cursor workspace/open lifecycle starter through a generated wrapper with empty stdout — expected { code: 1, … } to deeply equal { code: +0, stderr: '', stdout: '' } (line ~1109).

A third baseline failure — overview.e2e missing packageVersion after the #322 identity migration — was repaired in #332.

Verified on a clean detached worktree of current origin/main at fb25f47aaebd9e04b6d19febc088fbee7049c8a8 (after a fresh fetch and build).

Both exact commands from this report are green:

• examples-contract.test.ts: 1/1 file, 5/5 tests passed (including serves the routed Audiobook Curator artifact through a real MCP client), 0 failures.
• hooks.test.ts: 1/1 file, 25/25 tests passed (including runs the Cursor workspace/open lifecycle starter through a generated wrapper with empty stdout), 0 failures.

PR #328, merged as 3368b5b6a485506cc466ce4bb4920078a49db432 before this issue was filed, explicitly repaired both regressions: the #315 Audiobook route-count drift and the #298 generated hook wrapper/Rspack worker-URL path. This report's baseline was therefore pre-#328. Closing as already fixed by #328.

The separate Doctor AF_UNIX caveat is real: the current-node leg plus Rstest worker nesting produced a 118-byte pathname / 119-byte address including NUL, over Linux's 108-byte cap, and reproduced 4 socket-bearing Doctor test failures. Tracked separately in #335 as requested; it is distinct from these two regressions.
