feat(cli): add ork idp command for IDP inspection and validation

[iAlexeze]

Summary

Adds a new ork idp CLI command for inspecting and validating Internal Developer Platform (IDP) configurations, and consolidates global flag shadowing across all CLI commands with a reusable helper.

ork idp Command

Subcommands for inspecting and debugging IDP configurations without needing to run the gateway or access a cluster:

Command	Description
ork idp validate	Validate IDP configuration (--full for detailed breakdown)
ork idp schema	Show the flat schema for an IDP target (--target, --kind, --name)
ork idp fields	List IDP fields with their paths and types (--target, --kind, --name)
ork idp tokens	Show token permissions for a CRD (--target, --kind, --name)
ork idp targets	List all IDP targets in a Katalog
ork idp can-i	Check if a token can perform an operation
ork idp response	Show the IDP response configuration (--preview)

Flag Shadowing Consolidation

Introduces shadowGlobalCommandFlags(cmd, flags ...string) helper that recursively shadows global flags (debug, kubeconfig, verbose) on all subcommands, with optional support for command-specific flags like --file.

• Removes repeated manual flag shadowing from individual init() functions
• Prevents duplicate flag registration with Lookup() checks
• Commands can opt into additional flags (e.g., shadowGlobalCommandFlags(cmd, "file"))

Implementation Details

• All ork idp subcommands use buildKatalog() helper respecting --file
• resolveCRD() handles lookups by --target, --kind, or --name
• Colorized JSON output in response --preview
• Sorted field output for consistent display
• can-i validates namespace against CRD allowed namespaces

Example

# List all IDP targets
ork idp targets

# Show schema for a target
ork idp schema --target smartapp

# Check token permissions
ork idp can-i --token ci-pipeline --target smartapp --operation create --namespace staging

# Show response config with preview
ork idp response --target smartapp --preview

Test Plan

• ork idp validate passes on valid Katalog
• ork idp validate --full shows detailed breakdown
• ork idp schema -t <target> shows fields
• ork idp fields lists all fields
• ork idp tokens -t <target> shows permissions
• ork idp targets lists targets
• ork idp can-i correctly evaluates permissions
• ork idp response -t <target> --preview shows colorized JSON
• go build ./... clean
• go test ./... clean
• No duplicate flag registration panics
