Closes #654

Angular 22.2 changed @Component.deferredImports to an object that maps block names to classes, picked with @defer (name blk). OXC failed with Unrecognized trigger, and read only the old array form.

What changed

@defer (name blk)          → parser stores the block name (22.2.0-next.4+)
deferredImports: {blk:[A]} → a list per block
   ├─ full    → App_Defer_N_DepsFn per block (blocks with the same list share one)
   ├─ partial → deferBlockDependencies: [...] (outer block first)
   └─ linker  → links these files (before: left ɵɵngDeclareComponent unlinked, no error)

Case	Before	Now (matches ngtsc 22.2.3)
Named blocks, nested blocks, name before/after triggers	Unrecognized trigger	per-block deps in full, partial, linked output
imports:[C] + named block using C	error	C stays eager (named form defers no imports entry)
ns.X in a block list	—	read eagerly: () => [ns.X]
@defer without name / unknown name / name without deferredImports	no error	ngtsc's errors (11100 / 11101 / 11102)
Array form on 22.2.0-next.5+	accepted	error 1010
Object form before 22.2	ignored	'deferredImports' must be an array ...
Array form (≤ 22.1), partial	no deferBlockDependencies	emitted: every block gets the array's classes
Static import of a deferred class	kept	removed when deferredImports is the file's only use of it

name parse errors use Angular's text: Cannot specify multiple name parameters, Block names cannot be quoted in @defer blocks, Invalid block name "...".

Version gate

angularVersion	Array form	Object form	name
< 22.2.0-next.4	✅	error	Unrecognized trigger
22.2.0-next.4	✅	✅	✅
≥ 22.2.0-next.5, or unset	error 1010	✅	✅

⚠️ The Vite plugin passes angularVersion only when the user sets it. So a project on Angular ≤ 22.1 that uses deferredImports: [A] and does not set angularVersion now gets error 1010. Unset means "latest", the same as the other version gates.

Known differences from ngtsc (not changed here)

• Each block loads its declared list, in declared order (like ngtsc local mode). ngtsc full keeps only what the block uses, directives first. The runtime gets the same classes.
• An import line with other uses in the file is kept silently. ngtsc reports 8014 there.
• 8013 / 8012 (deferred class used outside @defer) and 2010 (not standalone) are not checked.
• A non-literal deferredImports: CONST is not evaluated; a named block then gives 11102, like ngtsc local mode.
• Under HMR or JIT the static import stays.

Verification

• Case matrix compiled with ngtsc 22.2.3 (full / partial / local) and with OXC. Linked output checked against Angular's linker.
• New tests/deferred_imports_named_test.rs (21 tests). Old array-form tests now set angularVersion 22.1.
• cargo test with and without --all-features, conformance 1264/1264, napi pnpm test 419/419, pnpm check.
