## Why
`update_goal` only accepted `complete` and `blocked`, preventing the agent from pausing a goal in response to an explicit user request.
## What changed
- Accept `paused` and account for final goal progress when pausing, with budget limits taking precedence.
- Update tool instructions and goal prompts to allow pauses only at the user's explicit request, report the returned status, and stop goal work. A later resume revokes the pause request.
## Testing
Extend coverage for pause accounting, budget-limit precedence, rejection of resume and system-limit statuses, and preservation of a tool-paused goal when resuming a thread.

## What changed
- Teach goal continuations to distinguish concrete progress, verified waits on live handles, and turns that made no progress.
- Re-poll live work after observation timeouts instead of treating the work as terminal or restarting it, and carry equivalent blockers through the existing blocked audit.
- Remove the duplicate goal prompt renderers and templates from `codex-prompts`; goal steering remains owned by the goal extension.

## Why
Goal steering prompts have grown into long inline Rust strings, which
makes the authored prompt text hard to review and easy to damage while
changing the surrounding plumbing. Moving those prompts into embedded
Markdown templates keeps the policy text in the shape reviewers actually
read, while preserving the existing runtime substitution and objective
escaping behavior.
## What changed
- Added `ext/goal/templates/goals/continuation.md`, `budget_limit.md`,
and `objective_updated.md` for the three goal steering prompts.
- Updated `ext/goal/src/steering.rs` to parse those embedded templates
once with `codex-utils-template` and render the existing goal values
into them.
- Kept user objectives XML-escaped before rendering and converted budget
counters into template variables.
- Added the template directory to `ext/goal/BUILD.bazel` `compile_data`
so Bazel has the same embedded prompt inputs as Cargo.
## Testing
- Not run locally.
