v0.3.3

Update proxer-cli to version 0.3.3 and enhance connection handling

• Bump version of proxer-cli in Cargo.toml and Cargo.lock from 0.3.2 to 0.3.3.
• Refactor connection handling in src/server/mod.rs by moving the termination of proxer-cli processes and command-line options parsing to the beginning of the run function for improved clarity and flow.
