* fix(tools): force UTF-8 output on fetch_page & robots_check (closes#685)
On Windows, a piped stdout (used by CLI runners like Claude Code)
defaults to the host ANSI code page (cp1252 on Western installs).
When fetch_page.py --text outputs a webpage containing non-Latin
or accented characters outside cp1252 (e.g. Polish, Danish, Cyrillic,
or CJK), printing the tag-stripped text failed with UnicodeEncodeError.
Similarly, robots_check.py lacked explicit UTF-8 stream configuration.
Address this by forcing UTF-8 encoding on standard output and error:
- tools/fetch_page.py: call _force_utf8_output() on startup
- tools/robots_check.py: add _force_utf8_output() and call it in CLI
- tests/test_tools_utf8_output.py: add regression tests for both tools
- CHANGELOG.md: document fix under Unreleased
All 770 unit tests pass, along with lint_skills and security_guards.
* changelog: place the #686 entry under [Unreleased]
