feat(workspaces): generated glyph icons for workspaces without a logo

[TheodoreSpeaks]

Summary

• Workspaces without an uploaded logo now get a generated glyph instead of their initial on a gray tile, so every workspace is recognizable in the switcher, search, org sidebar, invites, and resource menus
• Glyph is deterministic from the workspace id (stable across renames): one of three blob families (burst, ring, glyph) drawn with the same goo filter as the chat thinking loader, monochrome in the icon gray
• IdentityTile takes glyphSeed (workspaces) or initial (organizations, unchanged); uploaded logos still win
• Removed the now-unused getWorkspaceInitial

Type of Change

• New feature

Testing

• Rendered generator output at 16px in light and dark to confirm legibility
• glyph.test.ts: determinism, distinctness across seeds, every family stays centered inside the box, empty seed fails fast
• bun run lint, check:audits, type-check passing

Checklist

[Medium risk] Replaces workspace initials with generated glyph icons.

The PR appears safe to merge; the identified rendering-cost and test-coverage concerns are non-blocking.

Findings

1.  Repeated glyph rendering work ▶
2.  Rendered fallback remains untested ▶

Summary

The PR replaces initial-letter fallbacks for logo-less workspaces with deterministic, ID-seeded SVG glyphs across navigation, search, invitation, and resource surfaces. Uploaded logos retain priority; organization initials remain unchanged.

• The glyph generator has determinism and geometry tests.
• The switcher’s per-row rendering cost and the absence of component-level fallback tests merit follow-up.

Repeated glyph rendering work

The workspace switcher renders every filtered workspace. For each logo-less row, this component mounts a Gaussian-blur SVG filter and recalculates glyph shapes on every render, even when the workspace ID has not changed. Typing in the switcher repeats that work across the list, which can make larger workspace lists less responsive. Memoizing the glyph or limiting rendered rows would reduce the cost.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Rendered fallback remains untested

These tests call generateGlyph directly but never render IdentityTile. They therefore cannot catch a regression in uploaded-logo precedence or in how the SVG filter and shapes appear—the behavior users see. Component-level tests for a workspace with and without a logo would cover that gap.
