Add Support for `COLIMA_PROFILE` environment variable

[DrumRobot]

Description

Background

When working with multiple Colima profiles, it becomes necessary to switch environments quickly depending on the project.
Currently, there is no built-in support for specifying a COLIMA_PROFILE in the setup, which leads to repetitive manual work.

COLIMA_PROFILE is an environment variable that can be used to specify which Colima profile should be active.

Suggestion

Introduce a way to define and recognize the COLIMA_PROFILE environment variable automatically.
If set, the tooling should use the specified Colima profile instead of the default one.

Example

COLIMA_PROFILE=x64 colima start

Benefits

• Easier context switching between projects
• Reduced manual configuration steps
• More consistent developer experience
