Add tsessebe logo and pronunciation note to README

[mrjf]

Summary

• Add the project logo at assets/tsessebe-logo.png (1024×1024 PNG, transparent background) and render it centered above the title in the README.
• Add a one-line pronunciation note so newcomers know how to say the name.

# Tsessebe

> **Pronounced** *tseh-SEH-bee* · IPA /tsɛˈsɛbi/ — named after the tsessebe (*Damaliscus lunatus*), a southern African antelope. The word is Setswana; it carries the "ts" as one sound, the middle "se" takes the stress, and the final "be" is unstressed.

Test plan

• Confirm GitHub renders the logo at a reasonable size on the repo home page.
• Confirm the pronunciation line reads correctly (IPA, Setswana note, stress placement).
• Check dark-mode rendering — the logo has a transparent background so the dark fur should still be visible against GitHub's dark theme; if not, we can add a second light-mode variant later.

@copilot make the logo be to the left of the paragraph -- see how image / text alignment is done in https://github.com/githubnext/autoloop/blob/main/README.md

Updated in 38841c2 — the README now uses left-aligned image/text flow (matching the autoloop pattern) with a clear-left break after the pronunciation paragraph.
