feat(parser): add web and WebAssembly language support

[rabii-chaarani]

Summary

• build on the merged CSS support and add TypeScript, TSX, JavaScript, JSX, HTML, and WebAssembly Text in one cumulative change
• publish every language through source discovery, Tree-sitter parsing, syntax catalogs, CLI help, and the MCP schema
• preserve established TypeScript, JavaScript, and WebAssembly semantics while keeping HTML and CSS normalization conservative
• vendor the pinned Tree-sitter WAT grammar with scanner ABI fixes and recorded upstream provenance
• include focused materialization coverage and durable k-wiki parsing contracts for every added language

Verification

• cargo fmt --check
• cargo clippy --workspace --all-targets --all-features --locked -- -D warnings
• cargo test --workspace --locked (310 library tests plus all integration suites)
• cargo publish --dry-run --locked
• exact crate-size gate: 9,839,850 bytes <= 10,485,760 bytes
• recommended wiki validation, link check, and site build with zero diagnostics
