Summary by CodeRabbit

Chores
- Improved mobile CI/CD reliability by adding steps to free disk space and clean up Gradle build artifacts across build, deploy, and E2E workflows.
- Expanded Gradle caching paths to speed up Android builds and reduce cache misses.
- Enabled Corepack and prepared Yarn in E2E flows for more consistent dependency management.
- Overall impact: faster, more stable Android pipelines with reduced disk-space failures and cleaner post-build environments.

Walkthrough

Introduces two new composite GitHub Actions for freeing disk space and cleaning Gradle artifacts, expands Gradle cache paths, and wires these actions into multiple mobile workflows (CI, deploy, E2E, SDK demo). Also adds corepack enable/prepare for Yarn in one E2E workflow.

Changes

Cohort / File(s)	Summary of changes
Gradle cache action `.github/actions/cache-gradle/action.yml`	Expanded default Gradle cache paths to include `~/.gradle/caches/modules-`, `.../jars-`, `.../build-cache-*`, keeping `~/.gradle/wrapper`.
Actions: disk and Gradle cleanup `.github/actions/free-disk-space/action.yml`, `.github/actions/cleanup-gradle-artifacts/action.yml`	Added composite actions: one removes preinstalled toolchains to reclaim space; the other deletes Gradle build intermediates, daemon artifacts, locks, and temp files, then reports disk usage.
Mobile workflows `.github/workflows/mobile-ci.yml`, `.github/workflows/mobile-deploy.yml`, `.github/workflows/mobile-e2e.yml`, `.github/workflows/mobile-sdk-demo-e2e.yml`	Inserted “Free up disk space” before dependency/Gradle caching and Android setup; added “Clean up Gradle build artifacts” after Android build/verification. In mobile-e2e, added `corepack enable` and `corepack prepare [email protected] --activate` before `yarn build:deps`.

Poem

CI sweeps the runner’s room so clean,
Caches grow lean, yet builds stay keen.
Gradle crumbs vanish, disks breathe free,
Corepack whispers, “Yarn four point three… six!”
Pipelines hum—tidy, swift, and serene.
