Make proposed available by default? [was: Setting NotAutomatic for hirsute+1-proposed]

[Julian Andres Klode]

I expect apt commands to automatically download missing sources
in 24.10 or 25.04. It stands to reason we could add Disabled
sources too, and if you specify apt install foo/oracular-proposed
it just goes tweaks the bit, runs the update on it, and then
installs the package from it.

Also useful will be --no-strict-pinning such that you can use
apt install foo/oracular-proposed --no-strict-pinning to install
foo and satisfy as many dependencies from the release pocket as
possible*. You can use that with apt in oracular now. The next
version 2.9.5 should have some more improvements.

* This is formally an approximation. The APT solver 3.0 applies a
deterministic SAT solving algorithm with backtracking, which will
first try the candidate, then the installed version, and then ordered
by priority (including negative ones, fwiw) but it does not use MaxSAT
techniques to fully optimize the result. This means that given weird
dependencies, it could pull in more than strictly needed.
