1. Parser+codegen: bare reassignment `x = expr` inside an if-body
was compiling to three orphan expressions with no store. Now
emits a real assignment.
2. Runtime json_get: dot-path segments that are all digits now
correctly traverse array indices. `json_get(s, "0.field")` works.
3. Runtime HTTP writer: response bodies starting with
`{"__status__":<int>,...}` now set the HTTP status header to
that value and strip the marker from the served body. Existing
404/401/503 paths in product code now produce real status codes
instead of HTTP 200 with the status hidden in the body.
Self-host fixed point holds: gen2 == gen3 byte-identical.

Backlog: bl-c121edda
- New crate el-test: test discovery, in-memory graph seeding, assertion evaluator, TestRunner, TestReport with human/JSON/JUnit XML output
- New keywords: test, seed, assert, target — fully integrated into lexer, parser, codegen, type-checker
- Parser extensions: TestDef, SeedStmt, Assert AST nodes; seed blocks handle type: as field name (keyword-as-ident in seed context)
- Debugger: DebugEvent, Debugger, StepMode, StackFrame in el-compiler — breakpoints, step-over, step-into, step-out
- CLI: el test-file <file.el> runs tests; el test integrates with project; el debug attaches debugger; --output json|junit for CI
- 52 new tests in el-test covering discovery, graph seeding, assertion evaluation, pass/fail/error/skip, report generation, JUnit XML
- Example: examples/hello-project/src/tests.el — 6 unit tests pass, 1 e2e test correctly skipped without ENGRAM_URL
