Increase default Brainstore memory from 2 GiB to 4 GiB per CPU, matching the updated self-hosting sizing guidance. Readers and fast readers now request and limit 64 GiB with 16 CPUs; writers and automation writers use 128 GiB with 32 CPUs.

Update the GKE Standard, Autopilot, and Autopilot CEL examples, the README sizing example, and the automation-writer fallback defaults. CPU counts, replicas, storage settings, and chart/image versions are unchanged. Clusters using these defaults need enough node memory to schedule the larger pods.

Configuration behavior

Input	Behavior
AWS, GCP, Azure	All four pools render the increased default requests and limits.
Explicit resource overrides	Continue to take precedence; existing CI fixtures retain their custom sizing.
Enabled/disabled pools	Replica counts and enablement are unchanged, including the disabled-by-default automation writer.
Image tags: releases, SHAs, prereleases, custom tags	No changes to image handling or validation.
Upgrades with reused values	Explicitly retained resource values remain retained; the automation-writer fallback uses the increased memory when fields are absent.
Null/missing values, zero replicas, partial maps	Existing rendering and validation logic is unchanged; only the default memory constants change.

Validation

• Full ./test.sh: 419 Helm unit tests across 35 suites and 33 Python tests passed.
• AWS, GCP, Azure, and minimal CI profiles render successfully; strict Helm lint passes.
• Separately rendered all four pools with resource overrides removed on AWS, GCP, and Azure and verified CPU and memory requests/limits.
• Rendered all three updated deployment examples and the API autoscaling overlay with its required API version.
• Verified the default/example values only change Brainstore memory, and each configured pool uses 4 GiB per CPU.
• git diff --check passes. No live cluster deployment or scheduling test performed.
