fix: Add excludeChannels option to fix handlers registered before devtron.install() (#314)

[Dhanush010]

Problem

When IPC handlers are registered before devtron.install(), they receive wrapped payloads { __uuid__devtron, args } instead of original arguments. This breaks libraries like @bugsnag/electron that register handlers during module initialization.

Solution

Added excludeChannels option to InstallOptions that allows users to specify channels that should be excluded from Devtron's payload wrapping.

Changes

• Added excludeChannels?: Channel[] to InstallOptions interface
• Modified renderer to skip wrapping for excluded channels
• Modified main process to skip unwrapping for excluded channels
• Set up IPC handler to provide excluded channels to renderer

Usage

await devtron.install({
excludeChannels: ['bugsnag::renderer-to-main', 'bugsnag::renderer-to-main-sync']
});

Testing

• Verified excluded channels receive original arguments
• Verified non-excluded channels still work correctly

Fixes #314
