Minor Changes

• Add a curl installer (curl -fsSL https://hunk.dev/install.sh | sh) with checksum verification, and teach hunk update to update curl installs. (#799)
• Let extension commands inspect ctx.selection.currentLine; TypeScript authors constructing ExtensionReviewSelection must add its required field. (#779)
• Let extension commands capture immutable snapshots of stable review files and every saved review note. (#833)
• Add hunk update to self-update Hunk with the package manager that installed it (npm or Homebrew), with guidance for Nix, mise, and source installs. (#788)

Patch Changes

• Keep the active code line fixed in place while an inline comment form pushes following content down. (#809)
• Keep hunk --version, --help, daemon serve, and hunk session * off the diff-engine startup path again, and release the syntax worker when the review app exits instead of at startup. (#784)
• Make --fast offload eligible syntax highlighting for files with 40 or more lines. (#810)
• Let mouse clicks reliably select exact code lines, including blank lines, for keyboard review actions. (#840)
• Fail clearly when an OpenTUI upgrade removes the shifted-wheel scroll reset Hunk requires. (#786)
• Reduce hunk navigation latency by avoiding unnecessary diff, sidebar, and syntax-highlighting work. (#803)
• Reuse worker-highlighted diffs after the terminal cache evicts them. (#791)
