This change enables the Go adapter to embed platform-specific libraries
and extract them at runtime, eliminating the need for users to set
LD_LIBRARY_PATH or other environment variables.
- Add embedded.go with core library extraction functionality
- Update limbo_unix.go and limbo_windows.go to use embedded libraries
- Add build_lib.sh script to generate platform-specific libraries
- Update README.md with documentation for the new feature
- Add .gitignore to prevent committing binary files
- Add test coverage for Vector operations (vector(), vector_extract(),
vector_distance_cos()) and sqlite core features
The implementation maintains backward compatibility with the traditional
library loading mechanism as a fallback. This approach is inspired by
projects like go-embed-python that use a similar technique for native
library distribution.

### Problem
The Limbo Go driver currently throws an "unsupported type" error when
trying to bind `time.Time` values as query parameters. This requires
applications to manually convert datetime values to strings before
passing them to queries.
### Solution
Added `time.Time` support to the `buildArgs` function in `types.go`. The
implementation:
- Converts `time.Time` to RFC3339 format strings
- Uses the existing `textVal` type for storage
- Maintains compatibility with Limbo's datetime handling
### Example Usage
```go
// Previously failed with "unsupported type: time.Time"
now := time.Now()
db.Exec("INSERT INTO events (timestamp) VALUES (?)", now)
// Now works as expected
```
### Testing
I tested with various datetime operations:
- Parameter binding with time.Time
- Round-trip storage and retrieval
- Compatibility with existing datetime functions
Values are stored in standard ISO8601/RFC3339 format which I believe is
same as sqlite.

systems report x86_64. This change maps the architecture names to ensure the built libraries are placed in the correct directories for Go's embedded loading system (e.g., libs/linux_amd64)
