targrep 0.6.0

Added

• GitHub releases carry prebuilt Linux binaries (x86_64 and aarch64, glibc
  2.17 or newer) with SHA-256 checksums, built and smoke-tested by
  .github/workflows/release.yml on each tag. 0.5.0 was backfilled.
• x86-64 benchmark figures in the README: 9.4× less CPU than zgrep -a.
• Exclusion globs, as in ripgrep: a leading ! excludes, for both -g and
  --archive-glob (-g '!*.error.log', --archive-glob '!2026-09-*'). When
  several globs match, the last one given wins. With at least one non-!
  glob the list is a whitelist; with only ! globs, everything else is
  searched.

Changed

• A glob starting with ! used to be matched literally, so it matched
  nothing; it now excludes.
• rust-version = "1.88" is declared (the floor set by globset and
  ignore), so an older toolchain gets a clear error instead of a
  dependency failure. CI checks it.
