Add Emitter.emit calls

[ajbozarth]

Though we managed to add the emitter and include the emit calls in the agent and run context, we did not add them anywhere else. We should go through and reach parity with TS on emitter calls in locations that we already have implemented. On an initial pass that would include:

• context
• bee agent
• default runner
• backend chat
• tools base
• workflow

This was partially addressed in #360 to unblock the hackathon release, but I more detailed pass is still required. I plan to take some time away from examples tomorrow to work on this

Current Status:

• default runner will be finished by feat: retryable implementation #363
• backend chat will be fixed by feat: typings and error propagating #383
• tools base In TS the are 6 emit call in Tool.run but in python Tool.run does not wrap it's abstract _run call in a RunContext
• workflow In TS there are 3 emits inside Workflow.run but in python Workflow.run does not use RunContext and has no Emitter

@Tomas2D are the tools and workflow implementations temporary or intentional? Depending on your answer this can close once #363 and #383 are merged

Unblocks #391

@grahamwhiteuk i have unchecked tool base, workflow. from my understanding these do not yet have emitter

i noticed you checked all of them. is there something i missed? thx

[grahamwhiteuk]

@vabarbosa that's my mistake, I hadn't read Alex's comment thoroughly enough when I was checking through this morning.

@ajbozarth i think we should now be able to close this or are there any other work this needed?

[ajbozarth]

Closing this as #416 and #429 have closed out the remaining work. Emitters should be added alongside the features that use them from now on. Additionally I updated #431 to reflect the newly added events
