CLI: show task outputs (branch, PR, cost) when --watch completes

[axon-agent]

Problem

When using axon run -w (watch mode), the current output is:

task/task-a5b3c Running
task/task-a5b3c Succeeded

No indication of what the agent actually produced — the PR URL, branch name, commit SHA, or token cost are silently discarded. New users have to separately discover and run axon get task <name> to see results, which is not obvious.

The -w flag is highlighted in the Quick Start (axon run -p "..." -w) so this is the primary UX path for new users.

Fix

After the task reaches a terminal phase (Succeeded or Failed), watchTask now prints the populated result fields inline:

task/task-a5b3c Running
task/task-a5b3c Succeeded
  branch:              axon-task-a5b3c
  pr:                  https://github.com/org/repo/pull/42
  commit:              abc1234def
  cost-usd:            1.23
  input-tokens:        5432
  output-tokens:       1201

Only fields with non-empty values are shown. Tasks with no results (e.g. simple one-off prompts with no workspace) print nothing extra — no change in behaviour for those cases.

Test plan

• Added unit tests for printTaskResults covering: PR+branch+commit, cost+tokens, empty results, empty individual values
• make test passes
• make verify passes
