chore: add tilt

[adkah]

This PR configures Tilt in the repo.

Greptile Summary

This PR introduces Tilt as a local development orchestrator, adding a Tiltfile that wraps the existing bun scripts into named resources, along with supporting .tiltignore, VS Code extension, and language-association settings.

• Tiltfile: Defines resources for install, dev (hot-reload server), preview (build-then-serve), build, all check:* lints, and fix:* utilities. All referenced bun run script names match those in package.json. The check:writing resource is gated behind a runtime which vale guard with a graceful warn() fallback.
• .tiltignore: Excludes node_modules/, dist/, .astro/, agent/node_modules/, and *.log from Tilt's file-watcher.
• VS Code files: Recommend the tilt-dev.tiltfile extension and associate the Tiltfile filename with the tiltfile language mode for syntax highlighting.

Confidence Score: 4/5

Safe to merge — purely additive tooling config with no impact on the production build or runtime.

All bun run script names in the Tiltfile match the ones defined in package.json, the vale guard degrades gracefully, and the VS Code changes are non-breaking. The two minor points are the macOS-only install hint in the warn() call and the undocumented port-sharing constraint between dev and preview.

Tiltfile — the brew-specific install hint and the shared port between dev and preview are worth a quick look before merging.

Important Files Changed

Filename	Overview
Tiltfile	New Tiltfile defining local dev resources for install, dev server, preview, build, checks, and fix utilities; vale guard is platform-aware but the install hint is macOS-only
.tiltignore	Adds standard ignore patterns (node_modules, dist, .astro, agent/node_modules, *.log) to prevent Tilt from watching generated/dependency directories
.vscode/extensions.json	Adds tilt-dev.tiltfile extension recommendation alongside the existing astro-build.astro-vscode
.vscode/settings.json	Associates the Tiltfile filename with the tiltfile language so VS Code uses correct syntax highlighting

suggestion(non-blocking): your "build" resource doesnt seem useful, it's never used as a dep and the "preview" resource is already building
You could:

• remove the "build" resource
• or don't build in the "preview" resource and set "build" as a dep of "preview"

or don't build in the "preview" resource and set "build" as a dep of "preview"

This is what I wanted originally, but build was never running when I ran preview because build has auto_init=False - I'd have to manually run both

If it would be better to auto-init build I can do that, or just remove it and keep the build in preview?

This behaviour is really weird, I don't know why it does this
You can maybe remove the build and just keep preview, but that's ok actually
