Second pass over the page memory model (done by Codex/gpt-6-astra in an isolated worktree, reviewed and merged here): - Resize/reflow now port Zig's incremental ReflowCursor algorithm with page backfill and the same capacity growth/split sequence, instead of rebuilding a snapshot, so page boundaries, pruning and tracked-pin remapping match Ghostty. - Point<->pin conversion for the active area starts at the list tail and the viewport offset is cached, so hot-path operations no longer walk the whole scrollback from the head. - RefCountedSet reproduces Zig's observable ID reuse and error points. - All 202 PageList tests are ported (plus 13 extra regressions). With this, the five Screen/Terminal tests previously ignored as blocked on PageList behaviour pass and are re-enabled. Test Plan: - cargo test -p ghostty-terminal (913 passed, 0 ignored) - cargo clippy -p ghostty-terminal --all-targets -- -D warnings
