feat(bot): give GitHub and Linear their own session category instead of 'other'

[kilo-code-bot]

Summary

• Bot-spawned Cloud Agent sessions from GitHub and Linear were previously lumped into the "other" bucket in session filters and badges, because only 'slack' was in KNOWN_PLATFORMS.
• Added 'github' and 'linear' to KNOWN_PLATFORMS in cli-sessions-router.ts so the SQL NOT IN guard correctly excludes them from the "other" pseudo-filter.
• Added 'github' and 'linear' to PLATFORM_FILTERS in ChatSidebar.tsx (web) and platform-filter-modal.tsx (mobile) with their display labels.
• Added distinct session badges for 'github' (zinc) and 'linear' (indigo) in SessionsList.tsx.

Verification

1. Trigger a bot session from GitHub (or Linear) and confirm the resulting Cloud Agent session appears under the "GitHub" (or "Linear") filter tab, not "Other".
2. Check the session list badge shows "GitHub" / "Linear" instead of the purple "Extension" fallback.

Reviewer Notes

The createdOnPlatform value is already stored correctly as 'github' / 'linear' (set via thread.adapter.name in agent-runner.ts). This change only adds the missing recognition of those values in the filter/display layer.

Executive Summary

Straightforward addition of github and linear to KNOWN_PLATFORMS and PLATFORM_FILTERS arrays, with corresponding display labels and session badges. Change propagates correctly to all three consumer routers (cli-sessions, unified-sessions, cli-sessions-v2) via the shared import.
