Enhanced log streaming (multi-pod, search, follow)

[syedazeez337]

Summary

Upgrade log viewing with multi-pod tailing, log search/grep, and improved follow mode.

Motivation

stern is the go-to tool for multi-pod logs, but it requires a separate install. Building stern-like capabilities into KubeRift eliminates tool switching.

Requirements

Multi-Pod Logs

• When multiple pods selected (tab to multi-select), Ctrl-L streams all logs interleaved
• Prefix each line with pod name (color-coded per pod)
• Use: kubectl logs <pod> -n <ns> --tail=100 -f for each pod
• Merge streams chronologically

Log Search

• Within log view, allow /pattern to search/filter log lines
• Highlight matching lines
• Regex support

Follow Mode

• Ctrl-L enters follow mode by default (-f flag)
• q to exit, p to pause/resume, s to search
• Show line count and bytes received

Container Selection

• For multi-container pods, prompt: "Which container?" or "All containers?"
• --all-containers equivalent

Timestamps

• Option to show/hide timestamps: kubectl logs --timestamps
• Configurable in config.toml: [logs] show_timestamps = true

Acceptance Criteria

• Multi-pod log interleaving works
• Lines prefixed with color-coded pod names
• Search/grep within log output
• Follow mode with pause/resume
• Multi-container selection prompt
• Timestamp toggle
• Tests: verify log command construction
