📝 Walkthrough

Walkthrough

This PR introduces comprehensive Kubernetes resource management, a rebuilt plugin system with YAML manifest support, observability infrastructure for health and logs aggregation, and refactors the dashboard to support pluggable action execution. The changes span kubectl command wrappers, storage persistence, plugin discovery, monitoring snapshots, and UI action flows.

Changes

Kubernetes and Container Operations

Layer / File(s)	Summary
Kubectl Command Wrapper and Module Infrastructure src/kubernetes/command.rs, src/kubernetes/mod.rs	Foundation for all kubectl operations: run_kubectl executes commands with error context, non_empty_lines filters output, kubectl_list constructs resource queries.
Kubernetes Resource Modules (ConfigMaps, Deployments, Ingress, Namespaces, Secrets, Services) src/kubernetes/{configmaps,deployments,ingress,namespaces,secrets,services}.rs	List and get operations for six resource types with whitespace-delimited output parsing. Each module extracts name and metadata fields (e.g., ready, host) with sensible defaults when columns are missing.
Kubernetes Events, Pods, and Pod Operations src/kubernetes/{events,pods}.rs	Pod list/get/delete/logs with optional tail argument; event listing with reason and message extraction; logs returned as trimmed non-empty lines.
Configuration Paths and YAML-Backed Storage src/config/paths.rs, src/storage/sqlite.rs	New path helpers for command_history.yaml and project_cache.yaml. CommandHistoryStore records actions newest-first (capped at 100), ProjectCacheStore manages project roots newest-first (capped at 50), both with load/save and parent directory creation.

Plugin System Redesign and Manifest Loading

Layer / File(s)	Summary
Plugin Registry and Definition Structures src/plugins/registry.rs	PluginRegistry redesigned to hold structured PluginDefinition entries (with name, capabilities, menus) instead of plain name strings. PluginMenu includes id, label, and screen field. Registry provides names() and register() with deduplication and alphabetical ordering.
Plugin Manifest Loading and Manager src/plugins/{loader,manager,traits}.rs	load_from_dir() reads YAML/YML manifests from the configured plugins directory, parses into PluginDefinition, registers into PluginRegistry. load_installed() delegates to load_from_dir with fallback to empty registry. PluginManager provides load() and capabilities() aggregator. menu_items_from_registry() flattens plugin menus into MenuItem items.

Monitoring and Observability Infrastructure

Layer / File(s)	Summary
Health Reporting and Log Aggregation src/monitoring/{health,logs}.rs	HealthReport contains docker/kubernetes/registry status fields; overall() computes roll-up by priority (Critical > Warning > Unknown > Healthy). from_runtime() maps runtime flags to statuses. docker_logs(), compose_logs(), pod_logs() aggregate logs from multiple sources with standardized source labels.
Kubernetes Event Mapping and Monitoring Snapshot src/monitoring/{events,metrics}.rs	kubernetes_events() maps each Kubernetes event to MonitoringEvent combining reason and message. MonitoringSnapshot struct bundles health, metrics (via ResourceMetrics::empty()), logs, and events. snapshot() function constructs snapshots from runtime and provided logs/events.

Application State, Dashboard, and Startup Integration

Layer / File(s)	Summary
App State Runtime Refresh and Interactive Startup src/app/state.rs, src/main.rs	AppState::refresh_runtime() re-detects runtime and regenerates menus/actions. interactive_startup_options() forces force_first_launch: true in CLI default path, replacing prior cli.first_launch logic.
Dashboard Action Execution and Project Refresh src/ui/dashboard.rs	Refactors command palette and route_action to delegate to execute_action(), which navigates to screen, executes via KdcExecutor, updates status, displays output, and pushes success/warning notifications. refresh_project() reinitializes AppState while preserving theme and restarts scanning. Esc clears execution output; navigation keys clear before moving.
Extended kubectl Mock Support src/utils/test_support.rs	Expands KUBECTL_SCRIPT to mock deployments, pods, services, ingress, configmaps, secrets, namespaces, events, plus logs, delete, and scale operations.

Poem

🐳 Kubectl commands now flow through Rust's safe hands,
Plugins load from YAML files across the lands,
Health and logs converge in monitoring's light,
Dashboard actions execute with dashboard delight,
Yet parse those columns—watch the spaces right! 📊
