Move examples/*.sx and their expected/ snapshots into per-category subfolders (examples/<category>/...). Folder = leading filename token, with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus runner and LSP sweep now discover each category's expected/ dir, while issues/ stays flat. Example 1058's repo-root-relative companion import is made file-relative. Path strings embedded in 164 snapshots were regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// Regression (issue 0100 F2): lowering a QUALIFIED imported function whose
|
|
// body terminates must leave the CALLER's lowering state untouched.
|
|
//
|
|
// `m :: #import …` registers `m.foo` as a module-qualified alias with a unique
|
|
// FuncId (the identity fix, issue 0100 / example 0719) and lowers it through
|
|
// `lazyLowerFunction`'s null-FuncId `lowerFunction` path. `foo`'s body folds
|
|
// `if true { return helper(); }` to an unconditional return, so its lowering
|
|
// ends with `block_terminated = true`. The null-FuncId path used to restore
|
|
// every saved caller field EXCEPT `block_terminated`, so that flag leaked back
|
|
// into `main`, and `main`'s own trailing `print` / `return 0` were treated as
|
|
// dead-after-terminator — the compiler rejected `return 0` with "body produces
|
|
// no value". The fix routes all exit paths through one save/restore defer, so
|
|
// the qualified alias is transparent to the caller. (`helper` also lives in
|
|
// m.sx's own flat import, exercising the F1 source-context restore too.)
