[Bounty proposal] docs(cli): bring quickstart.ja.md up to the current localized template ($25 proposed)

Summary

sdks/python-cli/examples/quickstart.ja.md predates the current localized template (the one accepted for quickstart.fr.md / .pt.md / .it.md in #14219). Same situation as the German follow-up in #14215.

What the Japanese guide is currently missing versus the template, verified against omi_cli/:

• OMI_API_KEY precedence (env is used only when the active profile has no key — main.py get_profile)
• omi auth refresh scope (OAuth only; API-key profiles get a usage error, exit 1 — commands/auth.py)
• omi goal progress <GOAL_ID> <VALUE> and omi goal history (commands/goal.py)
• the top-level omi ask command (main.py)
• exit-code table: the current 1 row says "invalid flags, missing arguments", but those are caught by Click and exit 2; 1 is omi-cli's own validation (errors.py, main.py). The template's note about Click → 2 is also missing
• Bash exit-code example, permanent PowerShell env var
• local screenshot, local sql, and the local status → local tools → call flow (commands/local.py)
• profile precedence (--profile > OMI_PROFILE > active profile > default — config.py resolve_profile) and omi config show / path / set (commands/config.py)
• "Next steps" section

Scope

• Rewrite sdks/python-cli/examples/quickstart.ja.md section-for-section to the current template (10 H2 / 10 H3 / 21 code blocks, same as quickstart.fr.md)
• Keep every CLI command and flag byte-identical to the template; only prose and placeholders are Japanese
• No README changes needed (the ja links already exist in both indexes)

Proposed bounty

$25 (standard localized quickstart rate, same as #14215). I am a native Japanese speaker; PR is ready to open.
