feat(ui): add Microbridge logo and installer/tray icons

[DevVig]

What

Gives Microbridge a real brand mark and wires it through the desktop bundle so the installer, Dock, and menu bar all carry the identity instead of the placeholder icon — in time for the launch.

The mark

A focus-blue bridge on a dark squircle that doubles as a lowercase "m", with a glowing white live-signal node on the deck. The bridge is the product's mechanism (a neutral span connecting many agents to one deck); the lit node is its soul (live agent state rendered on the hardware). Dark tile matches the menu bar UI. Reproducible as SVG, verified legible at both 1024px (Dock/DMG) and 32px (tray).

Surface	Source
App icon master	docs/design/logo/microbridge-mark.svg
Menu bar glyph	docs/design/logo/microbridge-tray.svg

Changes

• App icon — regenerated the macOS/Linux icon set (icns, ico, PNG sizes) from the SVG master via tauri icon, and pointed bundle.icon at the full desktop set (was a single placeholder PNG).
• Tray glyph — the app icon is an opaque squircle and would render as a black blob under macOS template tinting, so the menu bar gets a dedicated transparent monochrome bridge silhouette. Tray now loads it via include_image!("icons/tray.png") instead of default_window_icon().
• Cargo.lock — synced this app's lockfile to the 0.1.0 workspace version (was stale 0.0.1).
• Scope is macOS + Linux only; no iOS/Android/Windows-Store tiles are committed.

Verification

• cargo check on the tauri crate passes.
• App icon and tray glyph both visually confirmed at Dock and menu-bar sizes.

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 1 minute

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Pull request overview

This PR introduces Microbridge branding assets (app icon master + tray glyph) and wires them into the Tauri desktop bundle so the installer/app icon and the system tray/menu bar icon reflect the new brand.

Changes:

• Added new SVG sources for the main app mark and a monochrome tray glyph under docs/design/logo/.
• Updated Tauri bundling config to use the full multi-size icon set (png, icns, ico) instead of a single placeholder PNG.
• Updated the tray icon code path to use a dedicated template-friendly tray image (icons/tray.png) and refreshed the Tauri crate’s Cargo.lock versions to 0.1.0.
