release(extension): v0.1.4 - README logo uses absolute GitHub raw URL

Open VSX renders the marketplace listing page's README on its own
site and doesn't resolve relative paths into the .vsix bundle. The
v0.1.0..v0.1.3 published listings at
https://open-vsx.org/extension/AxmeAI/axme-code show a broken-image
icon with the alt text "AXME Code logo" instead of the real logo,
because README.md uses a relative `media/icon.png` path.

Reported by @geobelsky 2026-05-19 after v0.1.3 publish: "the logo
is broken in one place but fine in another." The "fine" place is
the extension's icon inside Cursor (loaded from package.json "icon"
field by the IDE host, not from README — works correctly because
the .vsix DOES include the icon file). The "broken" place is the
Open VSX listing page rendering README.md.

Fix is the same as the one applied in PR #138 (e9f833d), which
never made it to main because that PR was closed without merge.
Lift it cleanly into v0.1.4:

  - extension/README.md: swap `media/icon.png` for
    https://raw.githubusercontent.com/AxmeAI/axme-code/main/extension/media/icon.png
  - extension/package.json: 0.1.3 -> 0.1.4

After this lands + tag push, the Open VSX listing page should
render the AXME logo correctly.
