refactor(cli): Replace tracing-indicatif with shared MultiProgress

tracing-indicatif pulled in vt100, arrayvec, and its own indicatif
integration layer. Replace it with a minimal SuspendingWriter that
coordinates tracing output with progress bars via a global LazyLock
MultiProgress.

- Add src/cli/progress.rs: shared MultiProgress singleton via LazyLock
  and a SuspendingWriter that suspends bars before writing log lines,
  preventing interleaving/flicker
- Wire all progress bar creation through multi().add() in sync and
  ingest commands
- Replace IndicatifLayer in main.rs with SuspendingWriter for
  tracing-subscriber's fmt layer
- Remove tracing-indicatif from Cargo.toml (drops vt100 and arrayvec
  transitive deps)
