add tree-sitter syntax highlighting via dart:ffi

Vendor libtree-sitter.so (v0.26.8, wasmtime 44.0 statically linked) and call its C API through dart:ffi. Grammar WASM files are loaded by tree-sitter's embedded wasmtime engine via ts_wasm_store_load_language. 48 grammars compiled with tree-sitter build --wasm, 48 highlight queries (42 from upstream repos, 6 written in-house for comment, erlang, gdscript, gitignore, hcl, hlsl, swift). SQLite grammar replaces full SQL (974K-line parser exhausted RAM at compile time). Removes wasm_run and wasm_run_flutter — they downloaded a 22 MB binary from GitHub at first launch, violating the no-network-on- default-launch-path policy.
