v0.2.0 — Resource Stats & Weight Classes

What's New

Resource Stats (-s / --stats)

New opt-in flag that adds memory usage, CPU time, and weight class grading to process listings.

merc -l -s
merc -json -s
merc -s       # interactive mode with ANSI colors

Weight Classes

Each process is graded into a weight class based on composite percentile rank (60% memory + 40% CPU time):

Class	Score	Color
feather	< 25th pct	dim gray
mid	25th–75th pct	white
heavy	75th–95th pct	yellow
wew lad	> 95th pct	red

JSON Output

When using -json -s, each process includes memoryBytes (uint64), cpuTime (nanoseconds), and weightClass fields.

Library API Changes

• ListProcesses now accepts a second collectStats bool parameter
• New GradeProcesses([]ProcessInfo) function
• New WeightClass type with constants
• New formatting functions: FormatBytes, FormatCPUTime, FormatWeightClass

Wiki
