feat(selfhost): HirNode.sourceFile for mid-function #line maps

Browse Source 
Stamp each HIR node with Decl source path; C backend tracks lastDebugFile
so #line re-emits when file or line changes. Closures inherit the
enclosing function path. Smoke checks Util_Double body maps to Util.bux.

# Bux — План към „добър“ език (v0.5 → v1.0)
> **Дата:** 2026-07-19
> **Текущо:** v0.5.x — multi-file #line, selfhost CI, **LSP 0.11 interface hierarchy**, Nexus KA
> **Текущо:** v0.5.x — HirNode sourceFile #line, selfhost CI, **LSP 0.12 path rename**, Nexus KA
> **Цел:** Език, с който се пишат реални проекти комфортно, безопасно (по избор) и с надежден toolchain.

## Сесия 47 (HirNode-level sourceFile / mid-function #line)
1. **`HirNode.sourceFile`** — per-statement path for `#line` (rare multi-file spans)
2. **`Lcx_StampSourceFile`**: after lowering a func/closure body, fill empty
node paths from `Decl.sourceFile` / `HirFunc.sourceFile` (keeps pre-set paths)
3. **`LowerCtx.currentSourceFile`** + closures inherit enclosing file
4. **C backend:** `lastDebugFile` + prefer `node.sourceFile` over func
`currentFile`; re-emit `#line` when **line or file** changes mid-function
5. `BUX_DEBUG_FILE` truly forces one path (no longer overwritten by per-func)
6. Smoke: `tools/smoke_selfhost.sh` — Util_Double body `#line` → Util.bux only
7. `make test-selfhost-smoke` / rebuild selfhost
