PR2 of two. Stacks on the context engine from PR1 and lands the user-facing features that make squeez attack input + output + memory-file tokens at maximum aggression by default. Highlights: - squeez compress-md — pure-Rust, zero-LLM caveman-style markdown compressor. Line-based state machine preserves fenced code blocks, inline code, URLs (bare + markdown link targets), headings, tables, list markers, and version strings; only natural-language prose is compressed. Drops articles + fillers + pleasantries + hedging everywhere. --ultra additionally substitutes with→w/, function→fn, configuration→config, repository→repo, etc. Damage heuristic aborts the write if any code block, URL, or heading was lost. Backups go to <stem>.original.md and are never overwritten. - Caveman persona — three intensity levels (lite/full/ultra) shipped via include_str!. Default is Ultra. Injected into the squeez init banner (Claude Code) and into the <!-- squeez:start --> block in ~/.copilot/copilot-instructions.md (Copilot CLI). - auto_compress_md=true — squeez init runs compress-md --all silently on every session start. Idempotent: backup is only written once and the integrity check guarantees safety. - squeez update — self-updater. Shells out to curl + sha256sum/shasum (both already required by install.sh) so we stay zero-dep. Atomic on Unix via .new + rename; documented .new + manual move on Windows. Override base URL via SQUEEZ_UPDATE_URL_OVERRIDE for tests. --check reports without installing; --insecure skips checksum. - squeez track-result + posttooluse hook update — PostToolUse now pipes the raw JSON for every tool call (Read, Grep, LS, Glob, ...) into squeez track-result, which extracts file paths + errors from the result content and feeds them into SessionContext. Future bash calls dedup against this state via the cross-call hint added in PR1. - Config additions: persona (default Ultra), auto_compress_md (default true). Both opt-out via config.ini. Tests: 230 passing (was 162). New integration tests for compress_md (13), persona (8), track_result (6), update (8). New mdcompress_* bench fixtures show ~22-27% reduction (caveman LLM gets ~45% with API calls; we get ~25% with zero API calls in <5ms). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
PR2 of the squeez token-optimizer roadmap. Lands user-facing features on top of the context engine from PR1 (#10, now merged).
squeez compress-md— pure-Rust caveman markdown compressor (CLAUDE.md, copilot-instructions.md, AGENTS.md). Line-based state machine preserves code blocks, URLs, headings, tables. Ultra mode adds abbreviations (with→w/,fn, etc.). Damage heuristic aborts write if code blocks / URLs / headings change.copilot-instructions.md. Default Ultra (most aggressive).
