v0.3.0

What's Changed

Added

• Process memory editing mode with --pid <PID> and --process <NAME> CLI flags, plus the :mem command family for attaching to, inspecting, and editing live process memory
• Memory panel views (region list, process picker, aggregated info report) with region highlighting and mouse interaction
• Memory freeze and thaw commands (:mem freeze / :mem thaw) to suspend and resume the target process
• Per-region editing state with :w / :q commit semantics; uncommitted replacements, undo, and redo are kept per region across switches
• Aggregated :mem info report across the whole session
• Memory search (:ms / :ms!) with gn / gN repeat, independent of file-search history
• Unified search command syntax (:s replaces the deprecated :S hex-search alias)
• Read-only synchronized diff page (:diff) comparing current logical bytes against another file
• Fixed hex column header (00 01 02 ... 0F) for quick column lookup while scrolling
• XOR selection command (:xor / :xor!) to XOR the active selection to clipboard or in place
• Performance benchmarks via cargo bench

Changed

• The repository source code is now dual-licensed under MIT OR Apache-2.0; full builds continue to use Keystone and now ship explicit third-party / FOSS notice / license / exception files under a dedicated licenses/ layout in release archives
• :export, :fill, and :xor! now stream output to avoid full materialization in memory
• Clean-document search uses SIMD memmem for faster scanning; only chunks containing tombstone or replacement edits fall back to byte-at-a-time
• Refactored app render, events, and commands for cleaner separation

Fixed

• Edit nibble no-op undo: editing a nibble no longer creates an empty undo entry
• Memory panel row mapping and scrolling now correctly track the cursor position
