CI: Refine workflows

[jserv]

ci.yml:

• Use uppercase display names (GNU/LLVM) with lowercase data values
• Add random delimiter for GITHUB_OUTPUT to prevent heredoc collision
• Skip QEMU install for LLVM (build-only validation)
• Simplify toolchain setup with shared lowercase name output
• Remove unnecessary permissions and redundant steps
• Improve cache key format for better organization

codeql.yml:

• Add concurrency control and timeout
• Add proper permissions (contents: read, security-events: write)
• Share toolchain cache with main CI workflow

Summary by cubic

Streamlined CI and CodeQL workflows for faster, safer runs. Standardized toolchain naming, improved caching, tightened permissions, and skipped QEMU for LLVM build-only checks.

• Refactors

  • Standardized toolchain names: display as GNU/LLVM, data/env as lowercase via shared output.
  • Improved caching: consistent riscv32- keys, actions/cache@v5, shared cache with CodeQL.
  • Adjusted execution: LLVM does build-only without QEMU; GNU installs QEMU and runs full app + functional tests.
  • Tightened permissions and simplified steps: removed unnecessary writes, cleaner summary flow, updated artifacts (download@v7/upload@v6) with 7/30-day retention.
  • CodeQL: added concurrency cancel, weekly schedule, 30-min timeout, proper permissions, and reused toolchain cache.

• Bug Fixes

  • Used random heredoc delimiters for GITHUB_OUTPUT to prevent multiline output collisions.

^{Written for commit 7672813. Summary will update on new commits.}
