Changes

• Read earlier game-file and pod output in pages of up to 100 lines and 64 KiB. File cursors pin the file and byte boundary. Pod cursors pin a timestamped record, pod UID and container instance, with bounded kubelet reads and explicit discontinuities.
• Page back into completed setup containers using the selected cluster and server permissions. File reads use the existing UID-bound agent transport.
• Offer Earlier output even for a short log. Open the live console immediately and display its independent pod snapshot separately, with a notice that the two streams can overlap or have gaps.

Verification

• Linux agent log package, including file replacement, truncation, appends and long UTF-8 records.
• API pod history, cluster guards and websocket package, including 600 writes between pages, same-name pod replacement, container restart and completed init containers.
• Dashboard Logs, Console and fixture suites (46 tests), end-to-end TypeScript check and the Vite production bundle. Chrome exercised loading an older page while live output continued. Both updated Pencil screens passed the visual comparison and pseudo-locale clipping checks.

Closes #936

Reviewed file cursors, pod and container identity, and the transition from history to live output. Tests cover an append between pages, copy-truncation during a read, repeated lines at a boundary, a large record followed by a short recent line, and bounded WebSocket replay. The Linux log-reader and API WebSocket suites passed. The Console and Logs Pencil exports show the history controls.

The file cursor can detect a change in the verified byte window. Rewriting an identical window on the same inode is indistinguishable to the reader.
