Description

This pull request primarily includes minor code style improvements and import ordering fixes across several files. The changes focus on improving code readability and consistency, particularly in conditional formatting and import grouping.

Code style and formatting improvements:

• Standardized spacing in if statements by removing unnecessary parentheses in multiple files, such as cmd/tracking/pause.go, cmd/tracking/stop.go, internal/storage/db.go, and internal/storage/models.go. [1] [2] [3] [4]
• Removed extraneous semicolons at the end of statements, e.g., in cmd/tracking/status.go.

Import ordering and grouping:

• Reordered import statements to group internal packages together and maintain a consistent style in several files, including cmd/entries/delete.go, cmd/history/stats.go, and cmd/tracking/start_test.go. [1] [2] [3]

Whitespace and minor cleanup:

• Removed unnecessary blank lines and improved whitespace for better code clarity, such as in cmd/entries/manual.go and internal/project/detect.go. [1] [2]
