BridgeJS: Fix argument order for stack-lowered imported parameters

… syntax (#792)

…origins (#795)

* BridgeJS: support importing from external ECMAScript modules

Extend `from: .module(...)` to accept bare specifiers like `node:path` or an npm package,
add `jsName: .default` for default exports, and emit named imports so a wrong export name
now fails at module-link time instead of at call time.

* BridgeJS: fix named-import regressions found in review

Do not require a module export for a wrapper-only `@JSClass`, since a named import is a
link-time requirement and nothing looks that name up; accept `jsName: nil` and the explicit
`.name(...)` spelling; and validate the tagged `from` form like the plain-string form.

* BridgeJS: split snippet and external module import origins

Use `from: .snippet("/my-file.js")` for a JavaScript file shipped with the Swift target and
`from: .module("node:path")` for an external module, so each keeps its own validation and
each mistaken form points at the other. The skeleton encoding is unchanged.

* BridgeJS: tag both snippet and module origins in the skeleton

Encode `.snippet` as `{"kind":"snippet","path":...}` alongside the existing tagged module
form, so the JSON mirrors the Swift cases and a snippet path can no longer encode into a
shape that fails to decode.

bridgeJSLowerParameter for structs used toJSObject(), so Swift→JS
callbacks discarded the stack and JS lift() read garbage. Match arrays:
stack-push on lower, and use the same ABI for ImportTS non-optional structs.

…ruct (#800)

BridgeJS: Support generic functions on imported JS APIs

An imported optional whose payload is stack-only ([T]?, [String: V]?,
@js struct?) used a hybrid convention: the isSome flag crossed as a wasm
i32 parameter while the payload was conditionally pushed onto the shared
stacks. Optional returns and optional array elements of the same types
already travel entirely on the stacks: payload first, then a 0/1 flag on
the i32 stack.

This lowers those parameters the same way. The Swift thunk pushes the
payload (if some) followed by the flag, the wasm signature carries no
argument for the parameter, and the JS handler pops the flag before
conditionally lifting the payload, through the same fragment already
used for optional returns and elements.

The hybrid shape was the last parameter category that both passed a wasm
argument and pushed stack data, which is what enabled the argument
transposition fixed in #794. Every stack-touching parameter is now
flagless and reverse-ordered, matching returns and elements. All other
optional parameter ABIs (scalars, strings, JSObject, closures, enums,
heap objects) are unchanged.
