Exchange::accept enqueued a pending ack whenever
!(duplicate && addressed && released) held, even when the backend
store.insert returned Err (store full / backend error). On Err the
released flag computed to false, so an ack was still enqueued: a
receiver that did not keep the message acked it. For an addressed
offer that releases the sender's custody for a message nobody holds;
for a broadcast it fires a false confidence event at the sender.
Gate the ack enqueue on res.is_ok(): enqueue only when the store
actually retained the observation. The existing released-holder
exception still applies among kept copies. No bounce is recorded on
Err (already the case).
Adds a unit test exercising a capped store (StoreError::Full) for
both a broadcast and an addressed offer, and a tines-sim property
that drives custody with CappedStore-backed nodes and asserts the
"at least one holder" invariant still holds when stores fill.
Revert on_ack release gating to release-on-any-ack (custody chain): release
custody on the first exact Ack from ANY peer the node dispatched the
observation to (relay or recipient), not just the recipient.
drain_ack_buffer send_n==0 bug: re-keep only the target addr's own pulled
entries instead of removing buffer.entries[0] (which dropped an unrelated
peer's oldest pending ack).
Rename the tines-sim addressed proptest to
addressed_always_held_by_carrier_or_recipient and reconcile its assertion to
the custody-chain holder invariant. Reword the misleading "Ids shrink
monotonically" comment. Add unit tests: ack_releases_custody_from_a_relay and
drain_ack_buffer_overflow_drops_only_target_peer.
Gate green: tines-core 106 lib tests, tines-sim suite, sh scripts/ci.sh.
Symlink the root Apache-2.0 LICENSE into tines-core and tines-sim so
`cargo package` includes the license text.

Bump tines-core and tines-sim to 0.2.0 (Peer::in_flight changed type).
Add CHANGELOG.md. README gains a "Writing a store" section and a note on
calling Exchange::on_send_error when driving Exchange without Node.

- Cut every fragment of a stream from one encoding (age frozen at the
first fragment) and bounds-check the slice: re-encoding mid-stream
corrupted fragments and could panic when the tick went backwards.
- Fold the bloom summary to fit the MTU instead of sending a ~540-byte
frame that small-MTU links reject; drop the sim's summary MTU
exemption that hid this.
- Finish a peer's in-flight stream before starting another, and count
an addressed message as delivered only after its last fragment.
- Alternate custody and broadcast per peer, rotate through addressed
candidates, and evict the oldest bounce record when full, so neither
path starves.
- Add Exchange::on_send_error; Node::poll uses it so Busy/Unreachable
sends are retried rather than silently dropped.
- Clear bounce records per contact, record duplicates against their
sender, and skip addressed messages that cannot fit the MTU.
