Bug: Runtime attribute needs to be more resilient to junk

[walmsles]

Bug Description

Need to sanitise the inputs from MCP client prior to validation. Need to trim whitespace from start/end of inputs and force lowercase.

Steps To Reproduce

When using MCP inspector can add \n to inputs which causes the search to fail with "Invalid runtime"

Same for mixed case spelling other than all lowercase.

Expected Behavior

When sending mixed case or whitespace padded data - the case and whitespace should be ignored and search to work correctly.

Actual Behavior

When sending runtime as "python\n" get error "invalid runtime"

Same for: "Python", "PYTHON"
