feat(config): implement global config to wire up config command

[Hweinstock]

Problem

The CLI is missing a way to view and control global configuration. There is an existing config command, but its not wired up.

Solution

• implement a new top level globalConfig/ module that defines an accessor for global config. The global config is decoupled from the source of the data via an injected dependency.
• move src/router/schemas.tsx to top level /parsing directory so that logic can be re-used.
• global config is type-safe based on the global config schema using json dot notation. For example, valid keys are telemetry, telemetry.enabled, etc. All of which are derived automatically from the schema definition.
• wire up config command to be output JSON responses.

Testing

• wrote unit tests at the config command level to test e2e, rather than testing implementation directly.
• e2e testing using existing config from CLI also works.
  Ex.

> bun run start config
{
  "telemetry": {
    "enabled": false,
    "endpoint": "https://telemetry.agentcore.aws.dev"
  },
}
> bun run start config telemetry.endpoint 
"https://telemetry.agentcore.aws.dev"

> bun run start config telemetry.endpoint https://example.com
"https://example.com"

Future Work

• add error types for telemetry, and easier reasoning (few todo comments on this).
• add logic to setup installationId for telemetry (getOrPut).

typecheck fixed in #1756 (comment)

[Hweinstock]

we could probably combine this with buildKeys above into a single traversal, but found it more readable this way.

[Hweinstock]

this test will be more useful once we have error types to signify permission issue vs parsing issue. checking the message feels flaky, so deferring this until we have error types.

[Hweinstock]

this is pretty close to a generalization of basetype helper above now that we extract inner type. I definitely think we can unify them, but left it OOS for this PR.

[Hweinstock]

this mirrors the behavior with git config AFAICT, if the value is unset, we don't print anything.

[Hweinstock]

rebased onto create command work.

I feel that the level of complexity this PR introduces is out of proportion with the functionality gained. Let's sync on this and see if we can develop a simpler approach.

I have some prior art here that might be useful to look at: https://github.com/AlexanderRichey/yagss/blob/main/internal/builder/config.go

[Hweinstock]

converted to draft while I rework based on offline discussion from above, will take out of draft when ready for another review.
