test(dist-bundle): assert inlined prompt content survives bundling

After the prompts-core migration the TypeScript prompt sources were
deleted; the only mechanism delivering markdown prompts to npm users
is bun build inlining via bunfig.toml [loader] ".md" = "text"
and import attributes. bun test runs from src/index.ts, not from
dist/index.js, so a future Bun upgrade that silently regresses
markdown inlining would pass source tests green while the published
bundle is broken with Cannot find module ../prompts/atlas/default.md
at first agent load.

Add a smoke test that scans the built dist/index.js for unique
signature strings from each migrated prompt file (15 signatures:
3 ultrawork + 5 atlas + 3 prometheus + 4 mode prompts). Skips
gracefully if dist/index.js does not exist (local bun test before
build). Wire into the existing CI Verify dist bundle tests step in
.github/workflows/ci.yml so the regression catches in CI build.

Closes pre-publish blocker V1 and V33.
