v1.1.0 — Interactive Console

The Interactive Console. polaris console opens a msfconsole-style REPL: a
block-letter ASCII banner in a randomly chosen color scheme (bundled art +
local randomness — no network, the Metasploit pattern), a polaris > prompt, and
commands to load a saved model bundle once and predict on raw text many times —
instant after the first load, unlike the one-shot polaris predict. Standard
library only (cmd + raw ANSI); color respects NO_COLOR and non-TTY output.

Added

• polaris.console: PolarisConsole (a cmd.Cmd REPL with load, predict,
  probs, info, exit/quit, and built-in help), render_banner (bundled
  block-letter art, five ANSI color schemes, seedable), and run.
• polaris console [--model BUNDLE]: open the console, optionally pre-loading a
  bundle.
