strings.Title is deprecated due to not handling Unicode properly.
Use cases.Title from golang.org/x/text for correct title casing.

Added golang.org/x/text v0.33.0 dependency.

Go 1.21+ has built-in min() and max() generic functions.
Remove the redundant custom implementations.

The isActiveSafe() method was only used in tests and exposed internal
implementation details. Refactored test to use behavioral verification
(checking no output is produced) instead of checking internal state.

Changed writeString to return (int, error) to properly handle
the io.WriteString return values. Callers explicitly ignore errors
using blank identifiers, making the intentional error handling clear.

This improves code transparency without changing behavior.

Add Go Reference badge linking to the official Go documentation
on pkg.go.dev for better API discoverability.

Add usage example for the Matrix component, demonstrating how to
create multi-row layouts for concurrent task progress. Updated
table of contents to include Matrix section.

Add project overview, key components table, build commands, testing
conventions, and code style guidelines for AI coding assistants.

Force added because GEMINI.md is ignored by global git settings.

Refactored title-related and error-handling tests to use table-driven
patterns for better maintainability. Switched to test.RandomString()
from gommons for consistency with other tests. Removed duplicate
test case.

Added a stress test to verify Matrix thread safety under concurrent row
updates. Also synchronized test helper usage by switching to
test.RandomString() across affected test files.

Introduced SpinnerBuilder to provide a more flexible and readable way
to configure Spinner instances. Updated tests to verify the builder.
