Devtree 0.2.0: Routing providers, canonical hostnames, and dev server runner selection

Devtree 0.2.0 introduces a pluggable routing provider system with Caddy support, canonical hostname support for remote access over Tailscale, configurable dev server runner selection, and new example projects.

Routing providers

• Added a pluggable routing layer that supports both Portless and Caddy as proxy providers, configurable via the new routing section in devtree.config.ts.
• Added Caddy process management with automatic route registration on dev and cleanup on exit.
• The doctor command now checks the configured routing provider and bootstraps it with --fix.
• The info command now reports the active routing provider and whether routing is enabled.

Canonical hostname and Tailscale proxy mode

• Added portless.hostname (and routing.hostname) config to assign a canonical hostname per checkout instead of the default .localhost URL.
• Added a portless-proxy Tailscale mode that exposes the dev server through Portless on a canonical hostname for remote access over a tailnet.
• Added the devtree hosts command to print the hosts-file entries needed for this checkout.
• doctor now verifies that the canonical hostname resolves and guides users to add local hosts entries via the new hosts command.
• The runtime environment now exports PORTLESS_PORT and PORTLESS_HTTPS so downstream tooling stays in sync with the active routing configuration.

Dev server runner selection

• Added dev_server.runner config (vite-plus or vite, default vite-plus) to choose which Vite dev server binary Devtree launches.
• VitePlus is now an optional peer dependency instead of a required dependency.
• doctor now checks that the selected runner is available on PATH.

Examples

• Added examples/simple-portless — a minimal Vite application using Portless with .localhost URLs.
• Added examples/caddy-hosts — a complete Caddy, Tailscale, hosts-file, PostgreSQL, and Redis setup with full setup guide.

Infrastructure

• Added Dependabot configuration for automated dependency updates; bumped the transitive yaml dependency from 2.8.2 to 2.8.3.
• Added a GitHub Actions workflow for npm release publishing using npm trusted publishing.
