build: Remove checked-in dist folder for dataobj-explorer

[cyriltovena]

Problem

The dist folder for dataobj-explorer is currently checked into git, creating maintenance issues:

• Code and dist can become out of sync
• Changes require manual rebuilds and commits
• Prone to human error

While this supports projects vendoring Loki via go mod vendor, we don't need the dist folder in Loki itself since assets are built in the Dockerfile.

Proposed Solution

Investigate using go:generate to:

• Remove dist folder from git
• Maintain compatibility with vendored projects
• Generate assets during build

Implementation Options

-Use go:generate to trigger asset building

• Add build step in go.mod/tools.go
• Update documentation for projects vendoring Loki

Immediate Improvements

Until fully resolved:

• Add CI check to verify dist matches source
• Create make target to validate sync status
• Add documentation about manual rebuild requirements
