TUT 0.0.4

TUT 0.0.4 hardens Unix terminal lifecycle handling and makes the remaining worst-case viewport work bounded and preemptible.

Highlights:

• pause and resume projected-row scanning, viewport location, and frame rendering while preserving atomic publication
• move visible search-highlight merging out of draw; each background merge phase performs at most 1,024 comparisons/output attempts
• reuse render, highlight, MatchBlock, checkpoint, and row storage with source-sized reservation bounds
• bound Unix terminal parser sequences to 64 KiB/2 seconds and retained events to 1,024 through the pinned crossterm fork
• terminate cleanly on terminal EOF/HUP with exact diagnostics, session logging, and cursor/alternate-screen/raw-mode restoration
• read commands from the controlling terminal without replacing fd 0, reject nested raw-mode sessions, and preserve inherited job-control signal behavior
• bind log files to resolved input path slots to resist rename-over, symlink, case/Unicode alias, and hardlink races
• retain Rust 1.88 as the MSRV and verify Linux/macOS, debug/release/overflow, PTY, package, install, and dist workflows

Known scope: process-global event-reader generation changes after replacing a tty in the same process remain tracked in issue #80; ordinary one-session CLI use is covered.
