refactoring(cli/tui): richlog visualizer

[VascoSch92]

What: Added _clean_and_truncate() that combines the repeated 3-step sequence:

strip + collapse newlines → truncate → escape Rich markup

into one call, replacing 8 inline occurrences in _extract_meaningful_title.

Why: The same 3-line pattern was copy-pasted for every event type branch, making the method 100 lines long and easy to
get subtly wrong (e.g., forgetting to escape or truncate in one branch). The helper makes each branch a one-liner and
ensures consistent processing everywhere.

Taste Rating: 🟢 Good taste

This is textbook refactoring: eliminates 8 instances of copy-pasted logic, ensures consistency, and makes each branch a one-liner. The helper name is clear, and the from_start parameter is used sensibly (file paths show filename, not directory).

Why this is good:

• Solves a real problem (maintenance burden + potential for subtle bugs)
• Simplifies without adding complexity
• No breaking changes (pure refactoring)

Verdict: ✅ Clean, pragmatic solution. Merge it.
