v0.4.0

Added

• Ten new comment languages:
  VB.NET, SQL, Lua, Ruby, Perl, PowerShell, R, Haskell, Elixir, and Zig,
  plus new C-family extensions
  (Kotlin, Swift, Scala, Dart, Objective-C, PHP, Groovy/Gradle).
• Configurable long-line advisory threshold:
  --long-limit N flag and SEMLF_LONG_LINE env var, 0 disables;
  default stays 120.
• install.sh: a curl-able POSIX bootstrapper.
  It clones or updates a checkout under ${XDG_DATA_HOME:-~/.local/share}/semantic-linefeeds,
  then hands the remaining arguments to scripts/install.py.
  --repo/--home/--ref (or SEMLF_REPO/SEMLF_HOME/SEMLF_REF)
  override the clone source, checkout location, and pinned ref for mirrors and reproducible installs.
• README rewritten around the install story:
  the curl one-liner leads,
  every adapter row links to its install guide,
  and a private-network path (mirror via --repo/SEMLF_REPO,
  Claude Code via a private marketplace remote) is documented.

Fixed

• Hook mode no longer flags files under the platform temp directory
  or any tmp/ path component,
  so agent-generated scratch and prompt files pass untouched.
