Dynamically patches codspeed build.rs during CI to use gnu11 instead of gnu17, addressing CodSpeedHQ/codspeed-rust#139 for older GCC toolchain compatibility in cross-compilation containers. Implementation: - Clone and patch codspeed v4.0.4 with retry logic - Validate build.rs and verify patch application - Inject [patch.crates-io] configuration at runtime - Platform-aware sed handling (macOS/Linux) - Update Cargo.lock for patched dependency The patch applies only during CI runs and does not persist in source control.

Move CODSPEED_TMP from system temp (/tmp) to workspace directory (.codspeed-patch) to ensure Docker containers used by cross can access the patched source. Add cleanup to remove temporary directory after use.

Fixes CodSpeedHQ/codspeed-rust#139 and #8858
bug: cross tool (used in our CI) ships with older GCC that doesn't support gnu17. Codspeed v4.0.4 hardcodes -std=gnu17 in its build.rs, causing builds to fail on i686-unknown-linux-gnu and x86_64-unknown-linux-gnu targets.
fix: our CI workflow now patches codspeed at runtime before building. It clones the codspeed source, changes gnu17 to gnu11 in build.rs, and tells cargo to use the patched version via a temporary cargo patch directive.
This unblocks our CI cross-compilation builds while we wait for upstream (CodSpeedHQ/codspeed-rust#139) to fix it properly. The patch is CI-only and doesn't touch our source tree.
