chore: Improve code quality and address linter feedback

This commit introduces several improvements across the codebase, primarily focused on enhancing performance, robustness, and developer experience based on static analysis feedback.

- Replaces `WriteString(fmt.Sprintf())` with the more performant `fmt.Fprintf` in the HTML and Markdown exporters.
- Enhances deferred `Close()` operations to log warnings on failure instead of silently ignoring potential I/O issues.
- Explicitly discards non-critical errors in test suites, particularly during file cleanup, to satisfy linters and clarify intent.
- Suppresses command echoing in `Taskfile.yml` for cleaner output during development tasks.
