GFI: Add automated task for building Helm chart dependencies in correct order

Summary Create a Taskfile command that automatically builds Helm chart dependencies in the correct order from child charts to parent charts.

Type Enhancement

Context Contributors must manually run helm dependency update for 8+ charts in specific order: leaf charts first (card-vault, web, monitoring, istio, keymanager, ucs), then dependent chart (hyperswitch-app), then umbrella chart (hyperswitch-stack). This manual process is:

• Time-consuming: Requires running commands for 8+ different charts
• Error-prone: Easy to miss charts or run them in wrong order
• Knowledge-intensive: Requires understanding the dependency hierarchy
• Friction for new contributors: Creates unnecessary barriers to getting started

The current dependency hierarchy requires this manual sequence:

# Step 1: Build leaf charts first
cd charts/incubator/hyperswitch-card-vault && helm dependency update
cd charts/incubator/hyperswitch-web && helm dependency update
cd charts/incubator/hyperswitch-monitoring && helm dependency update
cd charts/incubator/hyperswitch-istio && helm dependency update
cd charts/incubator/hyperswitch-keymanager && helm dependency update
cd charts/incubator/hyperswitch-ucs && helm dependency update

# Step 2: Build intermediate chart that depends on card-vault
cd charts/incubator/hyperswitch-app && helm dependency update

# Step 3: Build umbrella chart that depends on multiple charts
cd charts/incubator/hyperswitch-stack && helm dependency update

Starter tasks

1. Analyze the dependency hierarchy in charts/incubator/*/Chart.yaml files
2. Identify which charts have local dependencies vs external-only dependencies
3. Examine existing package-incubator-hyperswitch-helm task pattern in Taskfile.yaml
4. Create build order: independent → dependent → umbrella charts

Implementation hints

• File to modify: Taskfile.yaml (root level)
• Dependency order:
  1. Independent charts: hyperswitch-card-vault, hyperswitch-web, hyperswitch-monitoring, hyperswitch-istio, hyperswitch-keymanager, hyperswitch-ucs
  2. Dependent chart: hyperswitch-app (depends on card-vault)
  3. Umbrella chart: hyperswitch-stack (depends on app, web, monitoring, ucs)
• Task structure:

update-dependencies:
  desc: "Build all Helm chart dependencies in correct order"
  cmds:
    - echo "Building Helm chart dependencies..."
    - | 
       # add the chart building logic over here 
    - echo "All dependencies built successfully\!"
  aliases:
    - ud

• Error handling: Each helm dependency update should stop execution on failure

Acceptance criteria

• Task update-dependencies (alias ud) added to root Taskfile.yaml
• Dependencies built in correct order: leaf → intermediate → umbrella
• Command task build-dependencies passes locally after fresh clone
• All Chart.lock files are generated correctly
• Task provides clear progress feedback for each step
• Error handling stops execution if any chart fails to build
• Task works from any directory (uses proper cd commands)
• Test helm template charts/incubator/hyperswitch-stack works after running task

Resources

• Taskfile documentation
• Helm dependency command reference
• Existing task patterns in root Taskfile.yaml
• Chart dependency analysis: grep -r "file://" charts/incubator/*/Chart.yaml
