v0.8.4: procedural link-flags for cross-compile correctness

Message

Migrates link-flags: from (case (host-os) ...) to (lambda (ctx) (case (target-os ctx) ...)) so cross-compile builds (Linux → Windows via zig) pick the right branch at link time.

Before: (case (host-os) ...) evaluated once at package-load on the host, so a Linux host cross-compiling for Windows injected -lX11 -lXi -lXcursor into the final link and failed against zig's MinGW sysroot.

OS branches are unchanged: linux → -lX11 -lXi -lXcursor darwin → -framework Cocoa -framework QuartzCore windows → -lkernel32 -luser32 -lshell32 -lgdi32

Requires sigil-build 0.14.0+ (for target-os helper and procedural link-flags: dispatch in collect-native-link-flags).

### Fixed
+13
+14
- `link-flags:` now uses `(lambda (ctx) (case (target-os ctx) ...))`
+15
instead of a host-based `(case (host-os) ...)` expression. The
+16
host-based form evaluated at package-load time on the host, so
+17
Linux link flags (`-lX11 -lXi -lXcursor`) leaked into Windows
+18
cross-compile builds; `sigil build --config windows-amd64` from a
+19
Linux host would fail at the final link against zig's MinGW
+20
sysroot. The procedural form re-evaluates at link time with the
+21
target triple. Branches themselves are unchanged (`linux`:
+22
`-lX11 -lXi -lXcursor`; `darwin`: `-framework Cocoa -framework
+23
QuartzCore`; `windows`: `-lkernel32 -luser32 -lshell32 -lgdi32`).
+24
+25
### Requires
+26
+27
- `sigil-build` 0.14.0+ (for the `target-os` / `target-arch` helpers
+28
and the procedural-link-flags dispatch in `collect-native-link-flags`).
