refactor: rename template helpers from antigravity to devcontainer

Rename all Helm template helper functions from antigravity.* to
devcontainer.* to match the actual chart name. Also update Chart.yaml
description to remove "Antigravity" branding.

Renamed helpers:
- antigravity.fullname → devcontainer.fullname
- antigravity.pvcName → devcontainer.pvcName
- antigravity.envSecretName → devcontainer.envSecretName
- antigravity.labels → devcontainer.labels
- antigravity.smartResources → devcontainer.smartResources
- antigravity.smartDefaults → devcontainer.smartDefaults
- antigravity.mcpDefaults → devcontainer.mcpDefaults
