feat: default list_alerts to active alerts only

Change list_alerts (MCP tool) and alerts (CLI command) to show only
active (non-silenced, non-inhibited) alerts by default. Add state=all
option and --all CLI flag to show all alerts when needed.

- MCP: list_alerts with no state param now returns active alerts only
- MCP: list_alerts with state=all returns all alerts (previous default)
- CLI: alerts command defaults to active, --all shows everything
- Add tests for new default behavior and state=all option
- Update README with new CLI examples
- Bump version to 0.3.0
- Clarify version bumping rules in CLAUDE.md

 **IMPORTANT**: When running `nix build`, `nix run`, or similar commands, new files must be tracked by git first. Nix flakes only see git-tracked files. If you create new files, run `git add <file>` before attempting nix operations.
 
 ### Version Bumping
-Version bumps should be done once per feature branch, not per commit. Rules:
+Version bumps should be done once per feature branch, not per commit. **Only bump versions for packages that were actually changed** — different packages can have different version numbers.
+
+Rules for determining bump type:
 - **Patch bump** (0.1.0 → 0.1.1): Changes to Go code within `internal/` that affect a program
 - **Minor bump** (0.1.0 → 0.2.0): Changes to Go code outside `internal/` (e.g., `cmd/`)
 - **Major bump** (0.1.0 → 1.0.0): Breaking changes to CLI usage or MCP protocol
 
-Version is defined in multiple places that must stay in sync:
-- `cmd/nixpkgs-search/main.go`
-- `cmd/nixos-options/main.go`
-- `cmd/hm-options/main.go`
-- `cmd/lab-monitoring/main.go`
-- `internal/mcp/server.go` (in `DefaultNixOSConfig`, `DefaultHomeManagerConfig`, `DefaultNixpkgsPackagesConfig`, `DefaultMonitoringConfig`)
-- `nix/package.nix`
+Each package's version is defined in multiple places that must stay in sync *for that package*:
+- **lab-monitoring**: `cmd/lab-monitoring/main.go` + `internal/mcp/server.go` (`DefaultMonitoringConfig`)
+- **nixpkgs-search**: `cmd/nixpkgs-search/main.go` + `internal/mcp/server.go` (`DefaultNixOSConfig`, `DefaultNixpkgsPackagesConfig`)
+- **nixos-options**: `cmd/nixos-options/main.go` + `internal/mcp/server.go` (`DefaultNixOSConfig`)
+- **hm-options**: `cmd/hm-options/main.go` + `internal/mcp/server.go` (`DefaultHomeManagerConfig`)
+- **nix/package.nix**: Shared across all packages (bump to highest version when any package changes)
 
 ### User Preferences
 - User prefers PostgreSQL over SQLite (has homelab infrastructure)
