feat: add resource requests/limits support for cronjobs

[rohilsurana]

Motivation

The cron job container template doesn't expose resources, so cron jobs always run with no requests/limits — there's no way to bound their memory/CPU. This adds that support.

Changes

• Each cron job can define its own resources via cron.jobs[].resources.
• A chart-level default cron.resources is applied to every cron job and can be overridden per job.
• Precedence: cron.jobs[].resources → cron.resources → {}.

cron:
  resources:                 # default for all cron jobs
    requests:
      memory: 1Gi
  jobs:
    - name: light
      # inherits cron.resources
    - name: heavy
      resources:             # overrides the default for this job
        limits:
          memory: 6Gi
        requests:
          memory: 2Gi

Backward compatibility

Defaults to {}, which renders resources: {} — equivalent to the previous no-resources behavior. No change for existing users.

Verification

helm lint passes and helm template renders correctly:

• a job with no resources inherits cron.resources,
• a job with resources overrides the default,
• with neither set it renders resources: {}.

Chart version bumped 0.10.2 → 0.10.3; values and README updated.

📝 Walkthrough

Walkthrough

This PR adds configurable resource requests/limits for cron job containers in a Helm chart. A default cron.resources value and a per-job resources override field were added to values.yaml. The CronJob template now renders a resources block, defaulting to cron.resources and overriding with the per-job value when specified. The README was updated to document both new parameters, and the chart version was bumped from 0.10.2 to 0.10.3.
