v0.1.8

Day 50 milestone release — 51 commits spanning Days 36–49. Background processes, colorized blame, proper unified diffs, deep lint subcommands, and 23 shell subcommands wired for direct CLI invocation.

Added

• /bg background process management — launch, list, view output, and kill background jobs with persistent tracker (Day 45)
• /blame with colorized output — git blame with syntax-highlighted annotations (Day 48)
• /changelog command — view recent evolution history from the terminal (Day 44)
• /lint fix — auto-fix lint warnings (Day 46)
• /lint pedantic — extra-strict lint pass (Day 46)
• /lint strict — deny all warnings during lint (Day 46)
• /lint unsafe — scan for unsafe code usage (Day 46)
• 23 shell subcommands — help, version, setup, init, diff, commit, review, blame, grep, find, index, lint, test, doctor, map, tree, run, watch, status, undo, docs, update, pr — all invocable directly from the shell without entering the REPL (Days 48–49)
• Per-command bash timeout parameter — "timeout": N (1–600 seconds) for individual bash tool calls (Day 44)
• Co-authored-by trailer on /commit — automatically credits the AI in git commit metadata (Day 43)

Improved

• Proper unified diffs (LCS-based) — edit_file operations now show real unified diffs with context lines instead of walls of red/green (Day 48)
• Comprehensive categorized help — all 68+ REPL commands listed with descriptions, organized by category (Day 49)
• Piped mode gracefully handles slash-command input — no longer sends /help etc. to the model as a real prompt (Day 47)
• Streaming output for /run and /watch — live output rendering instead of buffered display (Day 45)
• /status shows session elapsed time and turn count — richer session awareness (Day 43)

Fixed

• Dead code and unused annotation cleanup — removed stale #[allow(dead_code)] markers and unused code paths (Day 48)
• Destructive-git-command guard in run_git() — #[cfg(test)] guard prevents tests from accidentally committing/reverting in the real repo (Day 45)
