Consolidate git repository helper functions into centralized utilities

[Copilot]

Duplicate git repository information resolution logic was scattered across compile_orchestrator.go, devcontainer.go, and git.go, with each implementing its own URL parsing and git root finding.

Changes

Centralized helpers in git.go:

• parseGitHubRepoSlugFromURL() - Parses GitHub URLs (HTTPS/SSH) to extract owner/repo
• getRepositorySlugFromRemote() - Extracts slug from current directory's remote
• getRepositorySlugFromRemoteForPath(path) - Extracts slug for specific file paths
• findGitRootForPath(path) - Finds git root containing a file

Refactored consumers:

• compile_orchestrator.go: Removed wrapper functions, all code now directly calls centralized helpers
• compile_validation.go: Updated to use centralized helpers directly
• compile_orchestrator_stability_test.go: Updated to use centralized helpers directly
• devcontainer.go: Updated getCurrentRepoName() and getRepoOwner() to use centralized functions

Example:

Before:

// In compile_orchestrator.go
func getRepositorySlug() string {
    cmd := exec.Command("git", "config", "--get", "remote.origin.url")
    output, _ := cmd.Output()
    url := strings.TrimSpace(string(output))
    url = strings.TrimSuffix(url, ".git")
    if strings.HasPrefix(url, "https://github.com/") {
        return strings.TrimPrefix(url, "https://github.com/")
    }
    // ... duplicate logic
}

After:

// In git.go - single implementation
func parseGitHubRepoSlugFromURL(url string) string {
    url = strings.TrimSuffix(url, ".git")
    if strings.HasPrefix(url, "https://github.com/") {
        return strings.TrimPrefix(url, "https://github.com/")
    }
    // ... handles both HTTPS and SSH
}

// In compile_orchestrator.go - direct call
repoSlug := getRepositorySlugFromRemote()

Original prompt

Review the function to resolve git repository information and reuse or refactor helpers from compile_orchestrator.go ( see getRepositorySlug others)

@copilot remove wrappers

Removed all wrapper functions. All callers now use the centralized helpers directly (fdb8f78).
