Reading `.has(k)` / `.get(k)` on a `signal.Set` / `signal.Map` / `signal.WeakMap` was subscribing to the signal atom instead of a per-key atom, so mutating *any* key (e.g. `signal.Set(...).add(2)`) re-ran every observer of the collection — even one that only read `has(1)`. The collection helpers in proxy.ts now pass `null` to onReadTargetKey / onWriteTargetKey, restoring per-key tracking. Shallow inner-value wrapping still respects the signal atom via possiblyReactive, so the existing "X item is not reactive" tests keep passing. Closes #1902

Spell out what signal.Array / signal.Object / signal.Set / signal.Map actually do: the proxy wrapping, the .set(newValue) replacement API, the shallow caveat, and — newly — the tracking granularity asymmetry. signal.Array and signal.Object invalidate the whole signal on any write; signal.Set and signal.Map track per-key, matching the behavior of proxy(). The latter was a documented-elsewhere assumption that confused users (cf. #1902); it now has a concrete example.
…ment signal.Array / signal.Object / signal.Set / signal.Map now default to an empty collection when no initial value is passed, so the common case of "reactive bag, fill it later" reads more naturally: const items = signal.Array<Todo>(); const cache = signal.Map<string, User>(); Suggested by seb-odoo in #1902 (Note 2).
