feat: add show command to display collected analytics directly in the terminal

[sebastienthibaud]

Adds a new “show” command/CLI that reads collected analytics (timers + human estimates) from spec folders and renders a consolidated report directly in the terminal.

Changes:

• Introduce src/show.ts to gather analytics from Markdown/JSON sources and render a terminal report (with optional project totals).
• Wire the show command into the controller/extension surface area, plus add a ska-show CLI and a bash wrapper script.
• Update docs and tests to cover the new show functionality; align Node built-in imports (node:*) and TS config.
