feat(components): move 6 API components to independent WASM Workers

Deploys gmail, telegram, line_notify, google_sheets, http_request, cron
as independent Cloudflare Workers at {name-kebab}.arcrun.dev. Each
wraps the TinyGo WASM from registry/components/{name}/main.go via
wasi-shim cross-import (Method A).

component-loader no longer carries BUILTIN_API_RECIPES — those
hardcoded gmail.googleapis.com / api.telegram.org / sheets / line-notify
endpoints all lived in TS, violating "all business logic in WASM".
Resolution chain now routes the 6 canonical IDs straight to their
{name}.arcrun.dev Worker URLs via WASM_HTTP_RUNNER_IDS.

Per .agents/specs/arcrun/credential-primitives-wasm Phase 3.
