Modernize zunit organization integration

[ss-o]

Summary

• add GitHub Actions coverage for native tests, syntax checks, and scheduled Zsh compatibility runs
• align user-facing behavior with current ecosystem usage, including dependency guidance, zunit init --github-actions, and safer HTML reports
• add regression coverage for CLI compatibility and report escaping while adopting Z-Shell modelines across Zsh sources

Test Plan

• ./build.zsh >/dev/null && PATH="/tmp/zunit-fake-bin:$PATH" ./zunit --tap tests
• find src -type f -name '*.zsh' -print | sort | while read -r file; do zsh -n "$file" || exit 1; done; zsh -n build.zsh; zsh -n zunit.zsh-completion
• git diff --check

Notes

• this keeps existing zdharma/* package coordinates where the surrounding ecosystem still uses them, rather than making an implicit namespace migration
• --travis remains available as a legacy bootstrap path; --github-actions is the new current example

Pull request overview

Modernizes the ZUnit project's CI/integration story for the Z-Shell organization mirror. It adds GitHub Actions workflows (native run, syntax check, scheduled multi-Zsh matrix), introduces a zunit init --github-actions bootstrap path, escapes test names/messages in the HTML reporter, defers the revolver dependency check so --help/--version work without it, fixes several "Supress" → "Suppress" typos and a zulu init → zunit init mistake, and adds Z-Shell-style modelines to all Zsh sources.

Changes:

• New CI: test-native.yml, zsh-n.yml, and a scheduled test-matrix.yml building Zsh from source in Alpine.
• zunit init --github-actions generator, completion entry, README walkthrough, and regression tests in tests/cli.zunit and tests/reports.zunit.
• HTML report escaping via a new _zunit_html_escape, deferred revolver check, dependency URL switch to zdharma/*, and assorted typo/comment fixes.

Applied all changes from the unresolved threads in commit 92b3461:

• src/reports/html.zsh: Changed echo "$value" to print -r -- "$value" in _zunit_html_escape so values starting with - or containing backslash escapes are handled correctly, and trailing newlines from command substitution are no longer silently dropped.
• .github/workflows/test-matrix.yml: Pinned the base image from alpine:edge to alpine:3.20 for a stable build environment, and added --retry 3 --retry-delay 5 to the SourceForge curl call to handle rate-limiting and transient redirects.
• README.md: Added a callout note directly below the intro paragraph explaining that the zdharma/* coordinates in install snippets are intentional — they reflect the package names still used by zplug/Homebrew at runtime — while z-shell/zunit is the active development mirror.
