marin-community/marin#1967 "Workspace" step 3: Ingest haliax as lib/haliax/

Third step in the "uv workspace migration plan" (#1773):

• Merge Haliax into lib/haliax/ (preserving full Git history)
• Migrate GitHub Actions workflows to monorepo structure
• Builds on: #1723 ("step 2", Levanter integration)
• Next step: Step 4 (Thalas executor)

(data_browser stays independent, not a workspace member)

Changes

• Merge Haliax into lib/haliax/ (preserving full Git history)
• Add Haliax member to workspace root pyproject.toml (alphabetized)
• Update Levanter's Haliax dependency to use workspace reference
• Migrate GitHub Actions workflows to monorepo structure:
  • Add Haliax workflows with haliax- prefix
  • Add "Haliax - " prefixes to workflow names
  • Update workflows for workspace structure
• Update pre-commit config with separate Haliax rules:
  • Preserve Haliax's line-length 119 config (vs Marin's 121)
  • Preserve Haliax's license headers separately
  • Exclude lib/haliax/ from Marin's general Python config
• Alphabetize workspace members and sources in root pyproject.toml
