Opt-in headroom-ai compression sidecar for tool results.

long-lived Unix-socket connection, newline-delimited JSON, multi-request (matches Rust client)
5s daemon-side timeout → degrades to uncompressed (None)
hardened python sidecar: 1 MiB guard, 0660 socket, graceful shutdown, robust errors
opt-in via COLIBRI_HEADROOM_ENABLED / COLIBRI_HEADROOM_SOCKET (default off)
2 new Rust tests (reuse-one-connection, timeout-fallback); docs/HEADROOM-SIDECAR.md

Reviewed: tests pass, fmt clean, py compiles, merges clean. The earlier full-clippy failure was the unrelated spawner.rs too_many_arguments lint, fixed separately in #56 (this branch does not touch spawner.rs).

- scripts/headroom-sidecar.py: Unix socket server (from headroom import compress)
- cost.rs: HeadroomSidecar struct with connect/compress methods
- session.rs: build_prompt_messages() now accepts optional sidecar
- daemon.rs: spawns sidecar on startup if COLIBRI_HEADROOM_ENABLED=true
- config.rs: headroom_enabled + headroom_socket_path config fields
- socket.rs: cmd_status reports headroom status, cmd_get_session uses sidecar
- All test fixtures updated with new DaemonConfig fields

40-50% token savings on tool outputs with zero accuracy loss.
Disabled by default (COLIBRI_HEADROOM_ENABLED=false).
Works identically on Linux and FreeBSD.

Keep the Python sidecar connection open for multiple newline-delimited requests, add daemon-side request timeout/fallback tests, and document the opt-in Headroom sidecar contract.\n\nChecks: ./scripts/check-format.sh; cargo fmt --check; python3 -m py_compile scripts/headroom-sidecar.py; git diff --check; cargo test -p colibri-daemon cost -- --nocapture; cargo test -p colibri-daemon session:: -- --nocapture; cargo test -p colibri-daemon --all-targets; cargo check -p colibri-daemon; manual sidecar two-request smoke using a headroom-capable Python env.
