- Make every statically-poked method public and call it directly,
keeping `public_send` only for dynamically-named public methods.
- Read and write state through public `attr_*` accessors instead of
instance variable reflection.
- Enable `Homebrew/NoSendInTests` and
`Homebrew/NoInstanceVariableAccessInTests` now the test suite is
clean, so neither pattern creeps back in.
- Keep rare justified disables, e.g. `Module#remove_const` is
private core Ruby and raw memoisation state has no accessor.
The library_paths method was using readlines which could leave file
descriptors open due to Ruby's garbage collection behavior. When
processing many packages during 'brew upgrade' or 'brew linkage',
this caused "Too many open files" errors on Linux systems.
Changes:
- Replace readlines with explicit file.open block to ensure proper closure
- Add caching to avoid repeatedly reading /etc/ld.so.conf during a session
- Cache included files as well to optimize recursive include processing

I think this is a bug in Ruby, but I've no idea how to track it down. I
can reproduce it intermittently in a codespace when `brew install`ing a
large number of formulae.
To work around this:
- cache the return value of `brewed_ld_so_diagnostics` so that we can
limit the number of calls to `IO.popen`
- retry once when we see a `TypeError`
Closes#17828.
