docs: add help documentation for 13 missing Makefile targets

[Copilot]

make help only displayed 12 of 25 user-facing targets. Development workflow commands like lint, e2e-tests, reviewable, and Docker build targets were undiscoverable.

Changes

Added ## Description comments to 13 targets:

Testing & Development:

• lint - Run fast linting
• staticcheck - Run static analysis
• e2e-tests - Run E2E tests
• e2e-tests-custom - Run custom E2E tests with labels
• setup-clusters - Set up Kind clusters for E2E testing
• clean-e2e-tests - Clean up E2E test clusters

Code Generation:

• generate - Generate deep copy methods
• manifests - Generate CRDs and manifests

Quality & CI:

• reviewable - Run all quality checks before PR

Docker Images:

• push - Build and push all Docker images
• docker-build-hub-agent - Build hub-agent image
• docker-build-member-agent - Build member-agent image
• docker-build-refresh-token - Build refresh-token image

Result

make help now displays all 25 targets, improving developer experience and discoverability.

<issue_description>### Describe the bug
Running make help only shows 12 of the 25 user-facing Makefile targets. Important commands for development workflows are not documented.

To Reproduce

1. Run make help
2. Notice important commands are missing

Missing targets (13):

• lint - Run fast linting (only lint-full is shown)
• setup-clusters - Set up Kind clusters for E2E testing
• e2e-tests - Run E2E tests
• e2e-tests-custom - Run custom E2E tests with labels
• clean-e2e-tests - Clean up E2E test clusters
• generate - Generate deep copy methods
• manifests - Generate CRDs and manifests
• reviewable - Run all quality checks before PR
• staticcheck - Run static analysis
• push - Build and push all Docker images
• docker-build-hub-agent - Build hub-agent image
• docker-build-member-agent - Build member-agent image
• docker-build-refresh-token - Build refresh-token image

Expected behavior

All user-facing targets should have ## Description comments so they appear in make help.

Screenshots

N/A

Additional context

The help target uses awk to find targets with ## comments. Adding ## Description after each target definition will fix this.</issue_description>
