docs: fix two markdown formatting errors in README

[redstartechno]

What problem does this solve?

Two small Markdown errors in the top-level README.md render incorrectly. One breaks an
italic caption; the other puts invalid text into a copy-paste shell command in the
"Build the project" section.

How do you know this is a real problem?

• Line 24 — the Diagram 1 caption opens emphasis with a single * but closes with **:
  *[Work in progress] Diagram 1. The Task flow [Source](docs/papers/InferenceFlow.png)**.
  The unbalanced markers mean the line does not render as intended italic.
• Line 52 — inside the fenced code block under "2. Build the project", the clone
  instructions read cd gonka (or repo name)**. The trailing ** and the parenthetical
  are stray editing leftovers; a reader copying the block runs an invalid command.

How does this solve the problem?

• Line 24: close the caption with a single *.
• Line 52: reduce the command to cd gonka.

What risks does this introduce? How can we mitigate them?

None. This is a documentation-only change with no runtime behavior impact. The change is
confined to README prose/formatting, so blast radius is a single file.

How do you know this PR fixes the problem?

Verified the rendered Markdown: the caption now renders as a single italic line, and the
code block now shows a clean, copy-pasteable cd gonka. See the before/after diff below.

Which components are affected?

README.md only.

Testing & evidence

No code paths changed; automated tests are not applicable to this documentation-only change.

Closing in favor of #1306, which combines this and the other docs fixes into a single PR per the maintainer's request. Thanks!
