feat(project-bootstrap): v1.2.0 — auto-load using-projects-meta in bootstrapped projects

CLAUDE.md template gains a fifth trigger line, `check across all projects`
(verbatim phrase from `using-projects-meta` description). Every new or
upgraded project now auto-loads cross-project task aggregation and shared
projects-wiki access without an explicit verbal trigger.

No Step 5.7 mirror of Step 5.6 (superpowers plugin recommendation):
`using-projects-meta` Prerequisites already self-corrects to
`setup-projects-meta` when MCP tools are missing.

Synced: assets/CLAUDE.md.template, inline copy in SKILL.md (Step 5),
README.md + README.ru.md trigger lists, this repo's local CLAUDE.md,
dist/project-bootstrap.skill, .wiki/concepts/projects-meta-skills.md
(Bootstrap trigger section), .wiki/log.md.

+The `check across all projects` line activates the `using-projects-meta` skill

+without an explicit verbal trigger. The skill is a no-op until the

 The `we're on Windows` line activates the `active-platform` skill and pins the
 project's default platform to Windows / PowerShell — so generated commands and
 README quick-starts use PS-native syntax. Bootstrapping on a Linux or macOS
