## Summary
- PCH compilation now serializes document links via `pch_links_json` in
`BuildResult` and stores them in `PCHState`
- Master server merges PCH document links with main-file links on
`textDocument/documentLink` requests, fixing missing links for
`#include` directives inside the preamble
- Adds document link support for `#embed` and `__has_embed` directives
## Test plan
- [x] Unit tests: `DocumentLink.Embed` and `DocumentLink.HasEmbed` added
- [x] Integration tests: `test_document_links.py` verifies PCH + main
merge and `#embed` links
- [x] All 483 unit tests pass
- [x] All 4 integration tests pass

`compilation/`, `features/`, `modules/`, `extensions/`, `stress/`
- Merge `test_include_completion.py` + `test_import_completion.py` →
`features/test_completion.py`
- Remove stale directory-tree comments and section divider comments

## Summary by CodeRabbit
* **Tests**
* Reorganized integration suites: added new feature tests (completion,
server) and removed older duplicated modules.
* Centralized shared test utilities and assertion helpers for
diagnostics, workspace operations, waiting/synchronization, and cache
inspection.
* **Chores / Refactor**
* Standardized test client lifecycle and helper usage across suites for
more reliable test flows.
* Improved server session lifecycle handling for more predictable
document/session resets during tests.
