Fixes #669.

In completion mode, overriding actor_rollout_ref.model.path changes the training model but previously left the GSM8K and Search-R1 agents using the tokenizer copied before the override was merged. For example, Search-R1 could train Qwen/Qwen2.5-3B-Instruct while its agent still encoded requests with the default Llama tokenizer.

Use ${actor_rollout_ref.model.path} for both tokenizer defaults so they resolve against the final configuration. Explicit tokenizer environment overrides retain precedence. Document this behavior in both examples.

Validation

On Windows with Python 3.12.10:

.venv\Scripts\ruff.exe check .
.venv\Scripts\ruff.exe format --check .
.venv\Scripts\python.exe scripts/check_headers.py
git diff --check

• Before their removal at maintainer request, the example regression tests showed 4 failed, 6 passed before the fix and 10 passed after the fix.
• Ruff, formatting, copyright headers, and diff whitespace checks passed again after removing the example test file. The earlier focused Pyright check also passed before removal.
• For the earlier regression run, SSLKEYLOGFILE was cleared only for the test process because the inherited local value points to an inaccessible log file.
• Full test suite, full-project type checking, documentation build, and real model inference/training were not run locally.
