The user asked to continue the piker broadcast-consumer audit after committing
the Deribit ownership fix. The next isolated item was IB's actor-local
`_quote_streams` cache, which retained a raw channel owned by its first caller
and constructed competing broadcaster roots for later callers.

> `git diff HEAD~1..HEAD -- piker/brokers/ib/feed.py`

Factored `_open_aio_quote_channel()` as the raw asyncio-channel context and
made `open_aio_quote_stream()` cache that context by symbol through
`maybe_open_context()`. Every caller now receives a lexical child from the
retained `LinkedTaskChannel` broadcaster, while the raw source remains alive
until its final cache user exits. Removed the manual `_quote_streams` registry
and teardown mutation.

> `git diff HEAD~1..HEAD -- tests/test_ib_broadcast.py`

Added a concurrent ownership regression using real Tractor broadcast state.
It proves miss and hit callers use the same symbol/context factory, receive the
same quote through distinct children, close independently, and leave the owner
live after the hit exits.

Verification output:

The new test passes through a source-isolated IB feed import. Test Ruff, E501,
Python compilation and whitespace checks pass. Normal package collection
remains blocked by the existing Qt environment mismatch.
