Remove unused export: isContainerStartupFailureError

[Copilot]

isContainerStartupFailureError in src/container-startup-diagnostics.ts was exported but never imported anywhere else in the codebase, making it dead public API.

Change

• src/container-startup-diagnostics.ts: Drop export from isContainerStartupFailureError, making it a module-internal helper. The function continues to be used within the same file.

// Before
export function isContainerStartupFailureError(errorMsg: string, containerName: string): boolean {

// After
function isContainerStartupFailureError(errorMsg: string, containerName: string): boolean {

Changes:

• Removed the export modifier from isContainerStartupFailureError.
• Kept the function in place and continued using it internally within the same file.
