v0.4.2 — honesty hardening + cost-accuracy fixes

A maintenance release closing a full pass of plan-tier-framing and cost-accuracy bugs found by checking TokenJam against real usage, plus first-class user pricing.

Highlights

• Honest plan-tier framing everywhere. Subscription/local users no longer see raw dollar figures across the CLI (tj cost) or the Lens web UI — Cost table, Traces, trace-detail, Status, and Optimize all suppress/reframe correctly; chart framing is consistent across time windows; CLI and Lens agree on the same data; axes read in local time with coherent daily labels. (#175, #176, #177, #178, #187, #188, #191, #197)
• Cost accuracy. Fixed LiteLLM provider attribution (was recording "litellm" → ~42% cost undercount, NULL billing account, suppressed plan); LiteLLM now also captures prompt/completion content and cache tokens. Imported sessions inherit the configured plan tier. (#183, #194, #195)
• First-class user pricing. Override per-model rates from your config — keyed by bare model name so it works even when the provider can't be inferred — with docs. (#200, #201)
• SDK & onboarding. The SDK honors TJ_CONFIG (no more writing to the wrong DB); onboarding / tj doctor surface when Claude Code needs a restart to start sending telemetry. (#179, #196)
