Move from 6.3-snapshot-2026-02-27 development snapshot to the official Swift 6.3.0 release.
Replace snapshot key mappings and embedded CI version overrides with direct release SDK references, URL, and checksum.
Remove snapshot-splitting logic. Read WASM_SDK and WASM_SDK_EMBEDDED directly from .swan-config.
Accept a download URL and checksum instead of parsing snapshot patterns. The swift sdk install command handles deduplication.
The version parsing now supports both release (X.Y.Z) and snapshot (X.Y-snapshot-DATE) formats from .swift-version.
Remove separate CI_TC_VERSION_EMBEDDED override. Embedded builds now use the same 6.3.0 release toolchain as all other workflows.
Remove references to development snapshot toolchain and the non-existent .wasm-sdk-version file. Document .swan-config and Makefile-based WASM build commands.

The embedded build needs to be fixed. It was working prior to this PR. |
- Remove snapshot fallback from Windows CI version parsing; only handle release format since .swift-version is now always X.Y.Z. - Restore embedded WASM to main-snapshot toolchain and SDK. Swift 6.3 has a compiler limitation with SPI conformances in embedded mode, so embedded builds still require a main-branch snapshot. Add sdk-install-embedded Makefile target with dedicated URL/checksum.
