[saturley-hall]

What type of PR is this?

• cleanup
• documentation

What this PR does / why we need it:

Adds a relative charts/snapshot/LICENSE symlink to the repository-level Apache-2.0 license and documents that it exists only for packaging. Helm dereferences the link into a regular file in the published chart archive.

Which issue(s) this PR fixes:

Fixes #358

How was this tested?

• make verify-crds verify-license-headers helm-lint verify-toc
• packaged the chart and verified snapshot/LICENSE is a regular file byte-identical to the repository LICENSE
• git diff --check

Special notes for your reviewer:

The full make check reached pagebroker-check-generated but could not execute the repository-bootstrapped protoc binary on macOS arm64. The targeted checks relevant to this change pass.

Does this PR introduce an API change?

NONE

Additional documentation, e.g. enhancement proposals, usage docs:

The root README now explains the chart-local packaging symlink.
