v1.1.1 — Documentation: Smart Call Completion & Wrap Selection demos

ℹ️ Docs-only release. Extension behavior is identical to v1.1.0.
If you are already on v1.1.0, there is no functional reason to
upgrade — this release exists to give two v1.1.0 features the
Marketplace-page visibility they deserve.

Documentation

• Two new feature sections in README with demo GIFs:
  • Smart Call Completion — auto-trigger procedure list after
    call (no Ctrl+Space needed). Accept expands into a snippet
    with parameter-name tab-stops.
  • Wrap Selection with Built-ins — select a variable, press
    Ctrl+Space, pick a built-in function → selection is wrapped
    as the first argument (active(x_pos) etc.). Works for all
    48 built-in functions via VS Code's standard $TM_SELECTED_TEXT.

Both features shipped in v1.1.0 but were only briefly listed under
"And More".

No code changes

237 tests green (unchanged from v1.1.0).
