- Remove /llgo from .gitignore (unnecessary)
- Move cgoSupported linkname to top with other linknames
- Fix goVersion initialization timing by making it local variable

Add linkname directives and stdlib comments for defaultToolTags and
defaultReleaseTags variables to match Go standard library pattern. This
allows external packages (like gopherjs) to access these internal variables
via linkname, maintaining compatibility with packages that depend on this
behavior.

Instead of creating a custom platform package, use the go:linkname
directive to directly link to Go's standard library internal/platform.CgoSupported
function. This approach:
- Eliminates the need to maintain a copy of platform support data
- Uses Go's canonical platform information directly
- Reduces code duplication and maintenance burden
- Follows Go's linkname pattern for accessing internal packages
Changes:
- Added import _ "unsafe" to enable linkname
- Added //go:linkname directive for cgoSupported function
- Removed custom runtime/internal/lib/internal/platform package
- Updated function call from platform.CgoSupported to cgoSupported

Created runtime/internal/lib/internal/platform package to house the
CgoSupported function, following the established pattern used by other
internal packages like internal/itoa.
Changes:
- Created runtime/internal/lib/internal/platform/platform.go
- Moved cgoSupported function to platform.CgoSupported
- Updated runtime/internal/lib/go/build/build.go to import and use
the new package
This refactoring improves code organization by separating
platform-specific utilities into their own package, making the code
more maintainable and reusable.

Replaced hardcoded goVersion constant with parseGoVersion() function
that dynamically extracts the Go version from runtime.Version().
This eliminates the need to update the version manually.

Learned from other AltPkg implementations to create a truly minimal patch:
- Moved from 2073-line overlay to 127-line hasAltPkg implementation
- Replaced internal package dependencies:
* internal/buildcfg → runtime.GOARCH/GOOS
* internal/goversion → hardcoded constant (24)
* internal/platform.CgoSupported → simplified implementation
* internal/buildcfg.ToolTags → simplified buildToolTags()
- Used type alias (Context = build.Context) to reference stdlib types
- Added go/build to hasAltPkg map
- Removed overlay entirely
This follows the pattern used by other AltPkg packages and achieves
the minimal patching approach requested.
Demo verified working with llgo.
