Collect some state

[retailcoder]

Picks up where the pipeline PR left off, so this is about exposing the collected state and notifying the LSP client.

✅ Done already:

• [x] Adjust DI/IoC to inject parser pipelines and their dependencies
• [x] Adjust workspace & document state management to have actual workspace state in WorkspaceStateManager
• [x] Run parser pipeline to successful completion
• [x] Collects syntax errors
• [x] Collects folding ranges
• [x] Collects document member symbols (modules, members, parameters)

✔️ Primary Objectives:

• [x] Resolves document member symbols
• [ ] Sends workspace/semanticTokens/refresh notifications

✔️ Secondary Objectives:

• [ ] Collects hierarchical symbols (statements, instructions, expressions, etc.)
• [ ] Resolves hierarchical symbols
• [ ] Collects semantic tokens

While resolving symbols is in-scope here, the main objective is to deliver the document symbols to the LSP client, along with any accumulated state - syntax errors, folding ranges, diagnostics, etc.; much of the necessary infrastructure is already in place, so much smaller diffs (vs previous pulls) should be expected going forward.
