feat: hapus fitur LSP bawaan (language server protocol)

Hapus seluruh pipeline LSP (client, manager, provisioner, dan 7 tool
lsp_*) dari codebase:

- apps/infrastructure/src/lsp/ (client.rs, manager.rs, provisioner/*)
- apps/infrastructure/src/tools/lsp/ (connect, disconnect, diagnostics,
  hover, completion, definition, references)
- ToolCtx/ToolCtxBuilder: hapus field lsp_manager
- Daemon state: hapus lsp_manager, lsp_provision_msgs, shutdown_lsp
- Registry: hapus registrasi 7 tool lsp_*
- Settings: hapus lsp_auto_provision + lsp_languages
- Agent definitions: hapus lsp_* dari allowed tools coder/reviewer
- Cargo: hapus dependency lsp-types (workspace + infra)
- Update dokumentasi mod + arch_audit forbidden list

Verifikasi: cargo check/clippy/test semua hijau (54 test), tidak ada
referensi lsp_* tersisa di luar CHANGELOG.
