v0.6.0

proc-daemon v0.6.0-beta — leaner metrics, cleaner core

A tidy beta that tightens the hot path (Prometheus exposition), cleans up lint debt, and standardizes formatting—no breaking API changes intended.

Highlights

• Faster Prometheus rendering with fewer allocations
• Clippy-clean across core modules
• Consistent formatting via cargo fmt

Changes & fixes

Performance

• Inlined format args for histogram count/sum names
• Removed redundant closure (Duration::as_secs_f64)

Correctness & hygiene

• Fixed duplicated cfg attribute in src/ipc.rs (feature gating centralized)
• Standardized formatting across the codebase (cargo fmt)
• General Clippy cleanup in core areas

Docs

• Added # Errors sections to unix::bind() and unix::connect() in src/ipc.rs
