v0.10.2: 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 -lasound into the final link and failed against zig's MinGW sysroot.

OS branches are unchanged: linux → -lasound darwin → -framework AudioToolbox windows → -lole32 -lwinmm -lksuser

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

### Fixed
+11
+12
- `link-flags:` now uses `(lambda (ctx) (case (target-os ctx) ...))`
+13
instead of a host-based `(case (host-os) ...)` expression. The
+14
host-based form evaluated at package-load time on the host, so
+15
Linux link flags leaked into Windows cross-compile builds; a
+16
`sigil build --config windows-amd64` pass from a Linux host would
+17
inject `-lasound` into the final link and fail against zig's MinGW
+18
sysroot. The procedural form re-evaluates at link time with the
+19
target triple, so cross-compile configs now pick the right branch.
+20
The OS branches themselves are unchanged (`linux`: `-lasound`;
+21
`darwin`: `-framework AudioToolbox`; `windows`: `-lole32 -lwinmm
+22
-lksuser`).
+23
+24
### Requires
+25
+26
- `sigil-build` 0.14.0+ (for the `target-os` / `target-arch` helpers
+27
and the procedural-link-flags dispatch in `collect-native-link-flags`).
