Bump CI memory limits for performance and demo (full) targets

[tomusdrw]

Summary

• Bump performance memory limit to 2048m for spacejam and jambda (mirrors the earlier jamduna bump in Bump jamduna performance memory to 2048m #43).
• Bump demo (full) memory limit to 8192m for all 23 targets — adds docker_memory: '8192m' where it was unset (default 2048m) and raises explicit values that were below 8192m. javajam was already at 8192m and is unchanged.

Test plan

• Manually trigger one of the demo (full) workflows via workflow_dispatch and confirm the target runs with the new memory limit.
• Manually trigger spacejam / jambda performance workflows and confirm the bumped limit takes effect.

Summary by CodeRabbit

• Chores
  • Increased container memory allocations for demo and performance workflows to improve stability and reliability (most demo runs now use 8192m; some performance jobs use 2048m).

📝 Walkthrough

Walkthrough

This PR uniformly increases Docker memory allocations across GitHub Actions workflows. Most demo workflows now allocate 8192m (8GB) to the reusable demo-source.yml workflow, while performance workflows allocate 2048m (2GB) to reusable-picofuzz.yml. This configuration change affects 25 workflow files spanning different targets.

Poem

🐰 I hopped through YAML lines today,
Poked in memory where containers play,
Eight gigs for demos, two for speed,
CI hums on, with ample feed,
Hooray — the jobs have room to sway!
