feat(lsp): hover signatures, go-to-def, document outline

Browse Source 
Upgrade bux-lsp to 0.2.0 with a richer lightweight symbol index:
func signatures, typed let/var/const, struct/enum/interface/type/module.
Skip comments and strings while scanning. Hover shows markdown Bux
code fences; definition resolves in-file and across workspace .bux files;
documentSymbol provides outline. Fix responses writing to stdout (stdin
was a broken pipe). didChange refreshes symbols; diagnostics still run
via buxc on open/save.

## Сесия 13 (LSP hover / go-to-def / outline — D.1)
1. **Richer symbol index:** `func` signatures (`params` + `-> Ret`), `let`/`var`/`const` with types, `struct`/`enum`/`union`/`interface`/`type`/`module`
2. **Skip comments/strings** during scan (no false `func` hits)
3. **Hover:** markdown ```bux signature``` + kind; accurate word range
4. **Go-to-definition:** current file + workspace index (scan `.bux` under rootUri)
5. **Document symbols** (outline) via `textDocument/documentSymbol`
6. **didChange** refreshes symbols immediately; **didSave/didOpen** still run `buxc check` diagnostics
7. **Fix:** responses write to **stdout** (was writing to stdin stream → broken pipe)
8. Version `bux-lsp` **0.2.0**; smoke-tested via JSON-RPC

## Следващи стъпки
1. **LSP hover / go-to-def** (над текущите diagnostics)
2. **Generic Iter map** (не само int), ако monomorphization с `func` params е стабилна
3. Struct/tuple patterns (`Point { x, y }`, `(a, b)`) + nested bindings
4. Match arm multi-stmt bodies (beyond single expr)
