feat: snap zoom levels + terminal tile summaries

[serefyarar]

Summary

• Replace free continuous canvas zoom with 4 snapping levels (33%, 50%, 75%, 100%) using ease-out-cubic animation
• Show terminal tile summaries (heuristic + optional LLM) when zoomed out to 50% or 33%
• Add PTY output capture, summary overlay UI with status-colored accents, and multi-tier display (detailed, reduced, compact)

Test plan

• Ctrl/Cmd+scroll zooms between the 4 snap levels with smooth animation
• Zoom indicator shows correct percentage at each level
• Terminal tiles show summary overlays at 50% and 33% zoom
• Summary overlays hide when zooming back to 75% or 100%
• Pinch zoom from tile webviews also snaps correctly
• Canvas state persists zoom level across reload

Not sure about the exact zoom levels (33/50/75/100) yet, but the main idea is that zoom should snap to discrete steps rather than free-scrolling. There should be some control/limit on how many levels there are and what they are — open to adjusting these.

TODO: Zoom level information density

The idea is that each zoom level should serve a distinct purpose by showing different levels of information:

• 100% — Full interactive view (current behavior, everything visible and usable -- code.)
• 75% — Slightly pulled back, still usable but tiles show condensed chrome/UI
• 50% — Overview mode: replace live content with rich summaries (terminal status, file previews, key metrics)
• 33% — Bird's eye: minimal badges/labels only, focused on layout and spatial awareness

Each step out should trade interactivity for context — zooming out should feel like gaining a higher-level understanding of what's happening across all tiles.

Bigger picture: zoom as a semantic interface

The deeper intent here is that zooming out should shift the interface from code/terminal-level interaction toward natural language driven building.

• Zoomed in (100%) — you're hands-on, writing code, running commands, interacting with raw output
• Zoomed out — the tiles become natural language representations of what's happening: summaries, status, intent, next steps — all in human-readable form

At the furthest zoom levels, you should be able to understand and direct the entire build process through language rather than reading terminal output or scanning code. The canvas becomes a high-level control surface where each tile communicates what it's doing and what it needs, and you can steer from there.

Zoom isn't just a visual scale — it's a shift in abstraction level.

Hey: this is a great idea that takes deep advantage of the unique interface of Collaborator. Will check out your PR. It's a big idea so it probably needs a bit of workshopping but it leads strongly in the direction I want to take this product, which is to help builders know what avenues to explore, not just help keep better track of the ones already set.
