Force Flux CD reconciliation via annotations and the Flux CLI

Steps

1. To force reconciliation via CLI, run 'flux reconcile source git {source-name} -n {namespace}' to pull the latest commits, then 'flux reconcile kustomization {kustomization-name} -n {namespace}' to apply them
2. To trigger reconciliation via kubectl annotation, add 'reconcile.fluxcd.io/requestedAt' with the current RFC3339 timestamp to the resource: 'kubectl annotate --overwrite kustomization/{name} reconcile.fluxcd.io/requestedAt=$(date -u +%Y-%m-%dT%H:%M:%SZ) -n {namespace}'
3. Monitor reconciliation progress with 'flux get kustomizations -n {namespace}' or 'flux get all' watching the 'READY' and 'MESSAGE' columns
4. Retrieve detailed events with 'kubectl describe kustomization/{name} -n {namespace}' to diagnose failed reconciliations
5. For HelmRelease resources, use 'flux reconcile helmrelease {name} -n {namespace}' or annotate the HelmRelease object similarly
