fix: correct log message when releasing browser with reuse=false (#112)

## Summary
- When releasing a browser with `reuse=false`, the CLI now logs "Deleted
browser X from pool Y" instead of the misleading "Released browser X
back to pool Y"
- The original "Released" message is preserved when `reuse` is not set
or is `true`

## Test plan
- [x] Run `kernel browser-pools release <pool> --session-id <id>
--reuse=false` and verify it says "Deleted browser ... from pool ..."
- [x] Run `kernel browser-pools release <pool> --session-id <id>` (no
reuse flag) and verify it says "Released browser ... back to pool ..."

> [!NOTE]
> **Low Risk**
> Only changes CLI logging text based on an existing flag; no behavior,
API calls, or data handling are modified.
> 
> **Overview**
> Adjusts the `browser-pools release` CLI success output to reflect
actual behavior when `--reuse=false`.
> 
> When `reuse` is explicitly set to `false`, the command now prints
*"Deleted browser … from pool …"*; otherwise it keeps the existing
*"Released browser … back to pool …"* message.
