docs(helm): Add commented hints for configuring an external Spider database in values.yaml.

[20001020ycx]

Description

The chart's values.yaml already hints how to point CLP at an external database (the clpConfig.bundled list plus the host/port comments in clpConfig.database), but there is no equivalent hint for the Spider subchart: its analogous switches (spiderConfig.bundled / spiderConfig.database) only appear in the subchart's own values.yaml, so they're easy to miss when configuring an external-database deployment.

This PR surfaces the Spider subchart's bundled / database settings under spider.spiderConfig in the chart's values.yaml, mirroring the style of the existing clpConfig sections (an active bundled list, plus a commented database template for the external case that otherwise defaults to the subchart's values.yaml), so users can discover how to externalize Spider's database alongside CLP's.

The chart version is bumped to 0.4.1-dev.7 (required by the chart lint for any change under the chart directory).

Checklist

• The PR satisfies the contribution guidelines.
• This is a breaking change and that has been indicated in the PR title, OR this isn't a
  breaking change.
• Necessary docs have been updated, OR no docs need to be updated.

Validation performed

The change is comments plus one explicit value — spiderConfig.bundled: ["database"] — which is identical to the Spider subchart's own default, so no rendered output changes; check 1 verifies that, and check 2 verbally describes the experiment in which the hinted configuration was exercised.

1. Render equivalence: helm template output is identical before and after this change.

2. The exact configuration the hints describe (uncommented, with real host/credentials) was exercised end to end on a single-node kind cluster: with spiderConfig.bundled: [] and spiderConfig.database pointing at an external MariaDB container (CLP's database configured external as well). We run a full log-ingestor S3 ingestion → Spider-orchestrated compression → API-server search flow succeeded — with a single external database instance serving both CLP's clp-db and Spider's spider-db schemas.

Walkthrough

The Helm chart documents bundled and external Spider database configuration. The chart version increases from 0.4.1-dev.6 to 0.4.1-dev.7.

Changes

Spider Helm values

Layer / File(s)	Summary
Spider database settings and chart release tools/deployment/package-helm/values.yaml, tools/deployment/package-helm/Chart.yaml	Adds Spider database bundling and external connection settings. Updates the chart version to 0.4.1-dev.7.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: 🔵 Low · up to 34e34

The external Spider database example uses localhost, which resolves to the Spider worker pod rather than the database host and can cause copied configurations to fail; the PR is otherwise mergeable with explicit owner follow-up to correct the example.
