Embed tree-sitter.wasm in CLI binary to fix bun --compile resolution

web-tree-sitter@0.25.10 split its package exports into separate `import`
and `require` conditions. In bun --compile binaries, require.resolve from
init-node.ts now returns the build-time absolute path of tree-sitter.cjs,
which doesn't exist on user machines, causing freebuff to crash on
startup with "Cannot find module .../tree-sitter.cjs".

Fix by embedding tree-sitter.wasm into the binary via Bun's
\`import ... with { type: 'file' }\` and stashing the resulting bunfs path
in process.env so all copies of init-node.ts (including the SDK pre-built
bundle's inlined copy) can pick it up.
