Shared logging initialization helpers.

Centralizes logging subscriber initialization. Libraries emit tracing events; binaries initialize a subscriber exactly once.

• init_stdout() – compact, human‑friendly formatting to stdout; respects KEYLESS_LOG or RUST_LOG
• init_json() – structured JSON output for GUI/backend use

keyless-logging = { path = "../keyless-logging" }

// in the binary (CLI or Tauri backend)
keyless_logging::init_stdout();
// or
keyless_logging::init_json();

// in libraries
tracing::info!("something happened");

TUI: the CLI initializes logging once at startup; the Dictating screen shows a rolling subset of log lines for quick inspection.

Env filters:

KEYLESS_LOG=keyless_whisper=debug,keyless_output=info
RUST_LOG=info  # fallback

This crate contains initialization helpers only; no tests are required.

• tracing for instrumentation
• tracing-subscriber for subscribers and formatting (human and JSON)

• src/lib.rs: init_stdout(), init_json(), and init_channel() helpers

Outputs to stdout/stderr across platforms.
