Fix issue-1: Update StopwatchApplication

[1imo]

Summary by CodeRabbit

• Style

  • Removed trailing artifacts from console output display.

• Bug Fixes

  • Live stopwatch display now consistently refreshes and clears previously printed characters when editing input or pressing backspace.
  • Console line updates are smoother and correctly reflect current elapsed time and input state.

Walkthrough

Introduces a private rendering state and a dedicated RenderLine(TimeSpan) method; RunAsync now calls RenderLine on iteration, Enter, Backspace, and character input. RenderLine formats elapsed time, appends the input buffer, pads trailing spaces using _previousLineLength, writes output, and updates _previousLineLength. No public API changes.

Changes

Cohort / File(s)	Summary
Console rendering refactor src/Stopwatch.App/StopwatchApplication.cs	Added private field _previousLineLength and private RenderLine(TimeSpan); replaced inline per-iteration/keypress console writes with calls to RenderLine; initialize _previousLineLength on Enter; update rendering on Backspace and character input. No public API changes.

Poem

🐰 I hop, I render, I tidy the line,
A little buffer, a timestamp that shines,
Old ghosts erased with a previous embrace,
Clean console footprints now leave the place,
Hooray for neat output — a rabbit's small rhyme.

Pre-merge checks and finishing touches

❌ Failed checks (2 warnings)

Check name	Status	Explanation	Resolution
Title Check	⚠️ Warning	The PR title "Fix issue-1: Update StopwatchApplication" correctly identifies that StopwatchApplication is being modified, but it fails to clearly communicate the primary change. The word "Update" is too generic and doesn't convey the specific nature of the change—which is refactoring the rendering logic to extract it into a dedicated private RenderLine method. While the title is partially related to the changeset (it mentions the correct file), it does not fully relate to or clearly summarize the main point of the change. A teammate scanning through git history would not understand what specifically was updated or why without clicking to view the details.	Consider updating the title to more specifically describe the refactoring effort, such as "Refactor StopwatchApplication rendering logic into dedicated RenderLine method" or "Fix rendering display issue in StopwatchApplication by refactoring to RenderLine method". This would immediately convey the nature of the change to anyone reviewing the commit history and better reflect the actual implementation details.
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	You can run @coderabbitai generate docstrings to improve docstring coverage.
