feat(cli): add configurable status line fields

[majal]

Summary

• add optional display.status_line field ordering for the live CLI status bar
• preserve the existing responsive Hermes status bar when status_line is empty or unset
• support Codex-style field names such as model-with-reasoning, current-dir, project-root, git-branch, context-usage, five-hour-limit, weekly-limit, fast-mode, used-tokens, and thread-title
• fetch account-usage/quota data off-thread and cache it so status rendering does not block
• document the new setting in the configuration guide

Test Plan

• python -m compileall -q cli.py hermes_cli/config.py
• python -m pytest tests/cli/test_cli_status_bar.py -q

Thanks for the configurable classic-CLI status-bar work. The feature is still absent on current main (cli.py:5055-5243; hermes_cli/config.py:1837-1854), but the implementation needs two corrections during salvage.

Problems

• cli.py:2529 falls back to the first account-usage window for five-hour-limit, and cli.py:2550 labels it 5h. Current main creates an OpenRouter window named API key quota in agent/account_usage.py:653-657, so this can mislabel a non-time-based quota.
• cli.py:1981-1983 caches the reasoning label only at startup. /reasoning changes self.reasoning_config and replaces the agent in hermes_cli/cli_commands_mixin.py:2541-2544, so model-with-reasoning can become stale.

Suggested changes

• Gate five-hour/weekly rendering on provider/window semantics and cover the OpenRouter case.
• Source the reasoning label from live state, with an in-session /reasoning regression test.
• Port the feature onto current status-bar/config locations rather than the April layout.

Automated hermes-sweeper review.

Do not fall back to windows[0] here. fetch_account_usage() also returns OpenRouter's API key quota window on current main (agent/account_usage.py:653-657), which this path will label as 5h at line 2550. Only render this field when the provider/window establishes five-hour semantics.

/reasoning changes self.reasoning_config and resets the agent without updating this cached value (hermes_cli/cli_commands_mixin.py:2541-2544 on current main). Derive the label from live state or update it in the handler so model-with-reasoning does not remain stale.
