## Observability

The stack defaults `observability.profile` to `compute`. The `compute` and
`all` profiles enable the NVCA collector and `BYOObservability` feature gate.
The `control` and `disabled` profiles leave both off.
`all` profiles enable the `BYOObservability` feature gate. The optional NVCA
collector stays disabled for every profile until the operator opts in. This
prevents a self-hosted install from depending on an image that was not mirrored
into its registry.

One value selects the normal behavior:

Explicit NVCA values override the profile defaults:
Enable the collector after publishing it under `global.image`. Its repository
defaults to `${global.image.registry}/${global.image.repository}/nvcf-otel-collector`:

Document the explicit image override in this section.

The example shows only enabled: true and global repository inheritance. Add global.nvcaOperator.selfManaged.otelCollector.imageRepository, or link to its existing documentation, so self-hosted users with a separate collector repository can use the supported override.

The PR objective states that explicit imageRepository overrides remain supported.

In `@deploy/stacks/nvcf-compute-plane/README.md` around lines 58 - 66, Update the
otelCollector configuration example in the documentation to include the
supported global.nvcaOperator.selfManaged.otelCollector.imageRepository
override, or link to its existing documentation, while preserving the enabled
setting and default global.image repository behavior.
