Release Lerim v0.2.0 context compiler runtime

[kargarisaac]

Summary

• reworks Lerim from coding-agent memory commands into a general trace-to-context runtime with ingest, curate, answer, and context-brief phases
• adds explicit custom trace import for JSON, JSONL, and text traces plus docs for custom-agent journeys and pre-cleaning
• updates README, docs, bundled skill, eval fixtures, tests, and BAML prompts around durable signal, business workflows, and all-agent usage
• removes legacy ask/maintain/sync implementation modules and cleans dead release code caught by vulture
