feat(work): pnpm work decompose subcommand

Closes the gap surfaced by the user: `pnpm work` usage referenced
`decompose` (via docs + the to-prd skill) but the subcommand was
never built. Mirrors `pnpm work dispatch`'s shape.

scripts/work/decompose.mjs (new):
  - validatePrdForDecompose(prdPath) — refuses draft (must go
    through human review first), in-review (review incomplete),
    shipped (epic already exists); accepts only approved
  - printDecomposePlan(prdId, prdPath, frontmatter) — print-mode
    output showing the PRD's eligibility + sandcastle invocation
    plan + auth modes
  - executeDecompose(prdId, prdPath, prdText) — invokes sandcastle
    with .sandcastle/decomposer.prompt.md, passing PRD_FILE_CONTENT
    promptArg. The decomposer agent writes the epic + per-story
    files to disk on a sandcastle branch the human can review
  - runCli(args, { workRoot }) — entry point used by cli.mjs
  - Direct invocation also supported (mirrors dispatch.mjs's
    invokedDirectly guard, NEW pattern after this commit)

scripts/work/decompose.test.mjs (new, 9 tests, all green):
  - validatePrdForDecompose: accepts approved; rejects draft,
    in-review, shipped, unknown status, missing file
  - runCli: writes error + returns 1 on missing PRD; writes error
    + returns 1 on draft PRD; prints plan + returns 0 on approved

scripts/work/cli.mjs:
  - Adds `decompose` subcommand to usage + dispatch
  - Usage formatting realigned for the 3-line subcommand block

scripts/work/dispatch.mjs:
  - **Fix** the bug surfaced by the user: dispatch.mjs's CLI ran
    as a top-level side effect whenever any of its exports was
    imported. decompose.mjs imports resolveClaudeAuth from it, so
    importing decompose.mjs printed "No ready task to dispatch."
    Added an `import.meta.url === \`file://${process.argv[1]}\``
    guard so the CLI only runs when invoked directly. This unblocks
    cross-import without side effects.

Smoke-tested end-to-end:
  - `pnpm work decompose` (no id) prints usage + exits 2
  - `pnpm work decompose 2026-05-13-binder-wrap-helper` prints the
    decompose plan with status: approved (eligible)
  - 9/9 unit tests green
  - dispatch.mjs's existing direct-invocation path unchanged
