feat: bump version to 1.2.18 and fix CPU process stats collection

[gaius-qi]

Description

This pull request introduces improvements to system resource monitoring, adds container-awareness to host announcements, and enhances logging for debugging. The changes include making CPU monitoring asynchronous, improving accuracy in CPU usage calculations, and ensuring cgroup stats are included when running in a container environment. Additionally, the pull request updates workspace versions and improves error messages.

Resource monitoring improvements:

• Refactored the CPU struct in dragonfly-client-util/src/sysinfo/cpu.rs to store physical and logical core counts, and updated methods (get_stats, get_process_stats) to be asynchronous for more accurate CPU usage measurements. CPU usage calculations now account for logical cores, and debug logging was added for detailed stats. [1] [2] [3] [4] [5] [6]
• Improved disk, memory, and network monitoring by adding debug logging for bandwidth, memory usage, and network stats in their respective files. [1] [2] [3] [4] [5] [6]

Container environment awareness:

• Updated SchedulerAnnouncer in dragonfly-client/src/announcer/mod.rs to detect if running in a container and include cgroup CPU and memory stats in host announcements, using new fields and logic. [1] [2] [3] [4] [5]

Dependency and version updates:

• Bumped workspace and dependency versions from 1.2.17 to 1.2.18 in Cargo.toml for all relevant crates. [1] [2]

Error handling improvements:

• Improved overloaded server error messages in dragonfly-client/src/grpc/dfdaemon_download.rs for clarity.
