feat: install dependencies from selected task

[0xth4nh]

What changed?

Runs the existing dependency installation command from the task selected in the signer UI:

- cwd: active/evm
+ cwd: active/evm/tasks/<task-id>

The existing missing-lib check, forceInstall behavior, and make deps command remain unchanged. Each task Makefile owns its BASE_CONTRACTS_COMMIT but sets PROJECT_DIR to the shared active/evm Foundry project, so dependencies still install where script/common expects them.

Checks

npx tsc --noEmit
npm run lint -- --no-cache
npm run build

Can't this PR just be a 1-line change here? Use resolvedTaskPath instead of resolvedUpgradePath ?

[0xth4nh]

Ahh yes! I think we can do that! I think the previous attempt, it tries to match the Makefile's current paths import such as:

../../Makefile      → active/evm/Makefile, which does not exist
tasks/<id>/.env     → tasks/<id>/tasks/<id>/.env
PROJECT_DIR         → tasks/<id>, causing dependencies to install in task/lib

But yah, we don't need to stick with the path and can change it!

Done in ac879b4. PR #188 is now exactly the one-line cwd: resolvedTaskPath change; the added route test and task-Makefile-specific command were removed. PR #755 now makes the task Makefile self-locating and points PROJECT_DIR/Forge workdir at shared active/evm.
