* Page evaluation result's output
This will make it easier to work with long output that exceeds the terminal's height.
* Use consistent TERM in rendering tests
This makes sure we get consistent result on all platforms.

* Remove trailing spaces
* Migrate show_source tests to integration tests
Because show_source tests often need to define class and/or methods,
they can easily leak state to other tests. Changing them to integration
tests will ensure that they are run in a clean environment.
* Fix NoMethodError caused by SourceFinder#method_target

prompt
(https://github.com/ruby/irb/pull/791)
Currently, IRB just terminates if `main.to_s` raises while IRB
constructs the prompt string. This can easily happen if the user wants
to start an IRB session in the instance scope of an uninitialized
object, for example:
```
class C
def initialize
binding.irb
@values = []
end
def to_s = @values.join(',') # raises if uninitialized
end
C.new
```
This patch makes IRB rescue from such an exception and displays the
class name of the exception instead of `main.to_s` to indicate some
error has occurred.
We may display more detailed information about the exception, but this
patch chooses not to do so because 1) the prompt has limited space,
2) users can evaluate `to_s` in IRB to examine the error if they want,
and 3) obtaining the details can also raise, which requires nested
exception handling and can be complicated.

If `output_modifier_proc`'s `complete` arg is true, it means the input is
submitted. In that case, debugger hint doesn't provide value to users
and adds noise to the output. So we hide it in such case.

Similar to Pry, it displays user-defined aliases in the help message with
a dedicated section. With the current default aliases, it looks like:
```
...other sections...
Aliases
$ Alias for `show_source`
@ Alias for `whereami`
```

With either `IRB.conf[:USE_PAGER] = false` or `--no-pager` commnad line flag.
I decided use `--no-pager` instead of `--use-pager` because it matches with
Pry and git's command line flags.

When user enters irb:rdbg session, they don't get the same hint that the
`debug` gem provides, like
```
(rdbg) n # next command
```
This means that users may accidentally execute commands when they want to
retrieve the value of a variable.
So this commit adds a Reline output modifier to add a simiar hint:
```
irb:rdbg(main):002> n # debug command
```
It is not exactly the same as `debug`'s because in this case the importance
is to help users distinguish between value evaluation and debugger command
execution.

I propose introducing the capability to set the IRB completion kinds via an environment variable, specifically `IRB_COMPLETOR=type`.
This feature aims to enhance the Rails console experience by allowing Rails users to specify their preferred completion more conveniently.
Currently, when using the Rails console, there's no straightforward way to globally set the type completion across a Rails application repository.
It's possible to configure this setting by placing a `.irbrc` file at the project root. However, using a .irbrc file is not ideal as it allows for broad configurations and can potentially affect the production environment.
My suggestion focuses on allowing users to set the completion to 'type' in a minimal.
This enhancement would be particularly beneficial for teams writing RBS in their Rails applications.
This type completer, integrated with RBS, would enhance completion accuracy, improving the Rails console experience.

After this change, `RubyLex` will not interact with `Context` directly
in any way. This decoupling has a few benefits:
- It makes `RubyLex` easier to test as it no longer has a dependency on
`Context`. We can see this from the removal of `build_context` from
`test_ruby_lex.rb`.
- It will make `RubyLex` easier to understand as it will not be affected
by state changes in `Context` objects.
- It allows `RubyLex` to be used in places where `Context` is not available.

`RubyLex` has always been a private component of IRB, so we should
explicitly discourage usages of it.
Also, it should be placed under the `IRB` module like other components.

integration
(https://github.com/ruby/irb/pull/688)
* Avoid overriding user's irb_name setting in debugger integration
Instead of always setting `irb_name` to `irb:rdbg`, it should respect
the user's setting and only append `:rdbg` to it.
* Introduce write_rc test helper
