feat(checksums): add loom 1.1.14 native binaries (#512) (#513)

loom v1.1.14 restored release binaries (loom#142) and ships native per-OS
tarballs + signed SHA256SUMS/cosign/SLSA/SBOM — but no loom.wasm (v1.x is
native-only). Add the 1.1.14 registry entry (tarball url_suffix per platform,
checksums from the signed SHA256SUMS.txt; linux verified against the actual
asset). The existing 0.3.0 wasm entry is preserved; @loom_wasm still pins 0.3.0
until the loom native toolchain + wasm_optimize rewire land (the rest of #512).

Step 1 of #512. Next: toolchains/loom_toolchain.bzl (extract tarball, expose
binary; mirrors meld_toolchain.bzl) + rewire wasm_optimize to the native loom
+ bundle bump to 1.1.14.
