[gobby-cli-#124] fix(ghook): Mark Windows extern block unsafe; release 0.1.1

ghook 0.1.0 published to crates.io but the Windows build target
failed: edition 2024 requires `extern "system" { ... }` to be
`unsafe extern "system" { ... }`. Local Mac dev never exercised the
#[cfg(windows)] branch in detach.rs so it slipped through.

Fix is one line in crates/ghook/src/detach.rs:36 plus a Cargo.toml
bump to 0.1.1 and a CHANGELOG entry. Linux/Mac use the
#[cfg(unix)] setsid(2) branch and were never affected -- the
crates.io 0.1.0 install works on those platforms but not Windows.

Verified: cargo build/test/clippy clean (27 ghook tests passing).
Once gobby-hooks-v0.1.1 is tagged, the Release ghook workflow
should succeed across all 5 build targets and create the GitHub
Release that 0.1.0 missed.

 - **Low-savings marker** — Suppress `[gsqz:low-savings]` marker when prepending it would grow the output beyond the original. The marker now only annotates when the annotation itself doesn't make things worse. (#111)
 - **Outer compression header for `/no-op` strategy** — When the low-savings marker is suppressed (above), the resulting `{pipeline}/no-op` strategy now also skips the outer `[Output compressed by gsqz — …, 0% reduction]` header and the daemon savings report. The user sees the original output verbatim. `CompressionResult::is_passthrough()` classifies `passthrough`, `excluded`, and `*/no-op` together so both call sites stay in sync. (#121)

+- **Windows build** — `crates/ghook/src/detach.rs` declared `extern "system" { fn FreeConsole() -> i32; }` for the Windows-only `FreeConsole()` call. Edition 2024 requires extern blocks to be marked `unsafe`, so the Windows build target failed under Rust 1.95. Mac/Linux unaffected (their `#[cfg(unix)]` path uses `setsid(2)` instead). 0.1.0 published to crates.io but Windows users could not `cargo install gobby-hooks`. (#124)
