v0.9.0

v0.9.0 — auto-harvested memories + SessionEnd distiller

ADDED

• Credentialed SessionEnd distiller (opt-in). A second, deterministic
  memory-harvest path alongside the v0.9.0 in-agent harvester. kimetsu plugin install claude-code and kimetsu plugin install codex now run an
  interactive wizard (on a TTY; skip with --no-setup, force with
  --setup-harvest) that configures a cheap distiller
  model: Anthropic (recommended claude-haiku-4-5), OpenAI (recommended
  gpt-5.4-mini), or compatible endpoints via ANTHROPIC_BASE_URL /
  OPENAI_BASE_URL. The key + base URL are written to a gitignored .env;
  the selection lands in [learning.distiller]
  in project.toml. A new SessionEnd hook for Claude Code runs
  kimetsu brain session-end-hook; Codex uses its supported Stop hook with
  --distill-on-stop. When enabled + credentialed, the distiller reads the
  transcript with that model and records lessons through the confidence-gated
  propose_or_merge_memory. When the distiller is enabled, the Stop hook's
  end-of-session cue is suppressed (the distiller owns end-of-session; the
  mid-session PostToolUse resolved-failure cue stays). AnthropicProvider
  gained an optional base URL for the LiteLLM case, and the distiller gained
  an OpenAI Responses API provider. With --scope global the
  wizard configures the distiller once in ~/.kimetsu/ (config + .env); that
  global distiller then runs in every project and records into the user brain
  (~/.kimetsu/brain.db, available everywhere), with a per-project distiller
  taking precedence when one is configured.
• Auto-harvested memories (in-agent). The hooks now drive memory
  generation, not just retrieval. When a command that failed earlier in the
  session succeeds (PostToolUse), or a non-trivial session ends with nothing
  recorded (Stop), Kimetsu emits a [kimetsu-harvest] cue telling the agent to
  dispatch a new background kimetsu-memory-harvester subagent (installed
  at .claude/agents/ for Claude Code and .codex/agents/ for Codex, pinned
  to a cheap model). The subagent distills 0–3
  generalizable lessons and records them through the confidence-gated
  kimetsu_brain_record path — no separate API key or kimetsu-side model
  credentials, billed in-agent at the cheap model's rate, non-blocking. Cues
  are throttled (at most ~once per resolved failure / once per session) and can
  be disabled with [learning] auto_harvest = false in project.toml.

CHANGED

• Cleaner help & tool menus. Stripped internal version-history prefixes
  (v0.x:, MP-…:) from --help text and the MCP tool/argument descriptions
  so menus read as plain present-tense descriptions. (Internal code comments
  are unchanged.)

FIXED

• Stop hook read the wrong field. The Stop hook counted
  kimetsu_brain_record calls from a non-existent inline transcript array;
  Claude Code actually passes a transcript_path to a JSONL file. It now reads
  the JSONL (with the inline array kept as a fallback), counts both the bare
  and MCP-namespaced (mcp__kimetsu__kimetsu_brain_record) tool names, so the
  "lessons recorded" banner and end-of-session cue actually fire. The JSONL is
  now streamed line-by-line so a long session's multi-MB transcript never
  lands in memory at once.
• BOM-tolerant install. kimetsu plugin install now strips a leading
  UTF-8 BOM before parsing an existing settings.json / hooks.json /
  config.toml / .mcp.json, so a config saved by a BOM-emitting editor
  (e.g. older Windows Notepad) no longer fails with "expected value at line 1
  column 1".
• Install polish. The installer now merges Kimetsu's guidance into an
  existing CLAUDE.md — workspace .claude/CLAUDE.md or the global
  ~/.claude/CLAUDE.md — inside <!-- kimetsu:begin -->/<!-- kimetsu:end -->
  markers, appending and upgrading in place, never overwriting the user's
  content. --force no longer overwrites CLAUDE.md (the whole install is
  idempotent and non-destructive; the flag is retained only for compatibility).
  A --scope global on the workspace-only kimetsu target warns instead of
  silently doing nothing; --workspace is canonicalized leniently so a global
  install doesn't fail on a missing workspace path.
