v0.0.7

Added

• custom provider — point bo at any OpenAI-compatible endpoint via bo config --provider custom --base-url <url> --model <model>. Any non-empty model id is accepted. Auth via CUSTOM_API_KEY env var or custom_api_key in ~/.bo/auth.json.

Changed

• Compile and collect diagnostics (title-collision warnings, branch-repair notices, pending-recovery notices, per-branch write progress) now print to stderr after the run completes instead of interleaved mid-run. Content and destination unchanged — only the timing shifts.

Fixed

• Tracing/diagnostic output now routes to stderr, keeping stdout clean for command output and --json parsing.

Architecture (non-user-facing)

• The engine is now the public library surface — a vocabulary of capabilities named for what they do, never for the command that invokes them. Query's retrieval, NLP, relevance, context-assembly, and citation-validation layers moved from cli to engine::retrieval with a semantic RetrievalError mapped at the CLI boundary.
• Presentation purity across all workflows: nothing below a command's entry point touches stdout/stderr; workflows return typed results and the CLI renders them. A TUI/REPL/web front-end can now compose the same primitives.
• Compile pipeline stages completed: validation extracted into a dedicated I/O-free trust-boundary module owning CompilePlan, and repair_stale_branches decomposed into a classify → prune → repair → assemble pipeline.
