feat(linkedin-studio): SB-S1 brain CLI — ingest + published list (init preserved) [skip-docs]

Add flag-routing infra (parseFlags) + two subcommands to the brain CLI, keeping
the existing `init` branch intact:
- `ingest --file <path> [--source] [--date]` / `ingest --scan-inbox` → capture
  published posts into ingest/published/ (Wrote / Duplicate / Collision report).
- `published list [--json]` → inspect the gold corpus (id · provenance · date · first line).
6 subprocess tests incl. an explicit `init` regression guard. brain 57→63 tests, tsc clean.

/**
* CLI for the second-brain foundation (SB-S0).
* CLI for the second-brain foundation + ingest (SB-S0 / SB-S1).
*
* node --import tsx src/cli.ts init
* node --import tsx src/cli.ts ingest --file <path> [--source <s>] [--date <YYYY-MM-DD>]
* node --import tsx src/cli.ts ingest --scan-inbox [--source <s>]
* node --import tsx src/cli.ts published list [--json]
*
* `init` scaffolds the `brain/` + `ingest/` tree under the per-user data dir
* (`LINKEDIN_STUDIO_DATA` overrides the root). Idempotent running it twice is a
* no-op. No session-start wiring yet (SB-S2 owns that); this is the invokable
* subcommand only.
* `init` scaffolds the brain/ + ingest/ tree (idempotent). `ingest` captures the
* user's published posts into ingest/published/ tagged provenance=published the
* gold signal the voice/profile-learning surface learns from (never ai-draft).
*
* Exit code: 0 on success, 2 on usage error.
