[0.12.1]

Added — periodic wake-ups, declared in the manifest

#[delegate(manifest(
    lifecycle = [NodeStarted],
    capabilities = [Background],
    wakeups = [heartbeat = 300],
))]
impl DelegateInterface for MyDelegate { /* ... */ }

• DelegateManifest::wakeups (WakeupSchedule { tag, every_secs }), written by #[delegate(manifest(wakeups = [tag = seconds, ...]))]. A node that implements it (a freenet-core release after this one) delivers InboundDelegateMsg::WakeupFired { tag } (wire tag 9, unchanged since 0.10.0) on that schedule with no app open, under the same conditions as lifecycle events: the manifest lists it and the delegate's app holds the user's Background grant.
• DelegateManifest::effective_wakeups is the node's reading: intervals clamped to [MIN_WAKEUP_INTERVAL_SECS, MAX_WAKEUP_INTERVAL_SECS] (60 s to 7 days), tags of 1 to MAX_WAKEUP_TAG_BYTES (64) bytes, a repeated tag keeps its first entry, at most MAX_WAKEUPS (4). The macro refuses out-of-range entries at compile time instead, and asserts them against the stdlib's own constants, so a macros crate looser than its stdlib fails to compile (and a stdlib without wake-ups has no such constants, so it fails too).
• DelegateManifest::with_wakeup and wants_wakeups.

Why a manifest entry, not a call. The 0.10.0 request half (DelegateCtx::schedule_wakeup, host import __frnt__delegate__schedule_wakeup) was removed in 0.11.0 because a delegate importing a function the node does not provide fails to instantiate. It stays removed. A manifest field is ignored by nodes that do not know it (the 0.12.0 reader skips unknown JSON fields), so one delegate build works on nodes with and without wake-ups: it loads and gets its lifecycle events everywhere, and receives WakeupFired only where the node supports it.

Compatibility. Patch release. No new host import and no wire-format change. A manifest without wake-ups serializes byte-identically to 0.12.0 (the field is omitted when empty), so upgrading changes nothing about the manifest SECTION. Rebuilding a delegate against a different stdlib still changes its WASM, and so its key, as any rebuild does (stdlib version strings end up in the module); plan the usual migration. Requires freenet-macros 0.3.1 for the wakeups argument.

Two things for authors targeting nodes that predate wake-ups (freenet-core v0.2.138 and earlier): such a node asks for Background only when a lifecycle kind is listed, so declare one (e.g. NodeStarted) alongside wakeups; and it stores the manifest re-serialized without wakeups, so the node that adds
