yiliang114 c1004d0e99 fix(lsp): improve C++/Java/Python language server support
Key changes:

1. Remove LspLanguageDetector — LSP is now fully config-driven via
   .lsp.json or extensions. No more auto-detected built-in presets
   that fail when the server binary is missing.

2. Add ensureDocumentOpen — send textDocument/didOpen before every
   document-level LSP request (definitions, references, hover,
   documentSymbol, implementations, prepareCallHierarchy, diagnostics,
   codeActions). This fixes the root cause of most methods returning
   empty results (Issue #2106, #1873).

3. Add retry mechanism for slow servers — when a freshly opened
   document yields empty results on non-TypeScript servers (jdtls,
   clangd, pylsp), wait 2s and retry once. This mirrors the existing
   retry logic in workspaceSymbols.

4. Handle LSP 3.17 WorkspaceSymbol format — location.range is now
   optional in normalizeSymbolResult, fixing jdtls workspace symbol
   responses that omit the range field.

5. Improve workspace symbol warmup — for non-TypeScript servers, open
   a workspace file before the first workspace/symbol request and
   retry on empty results after a warmup delay.

6. Track warmup-opened URIs — warmupTypescriptServer now returns the
   opened URI, which is registered with ensureDocumentOpen to prevent
   duplicate didOpen notifications.

Closes #2106, closes #1873
