fix(ci): update CH32V path filters after crate split

[zackees]

Closes #1107

Summary:

• update common and family path filters to the split crate layout
• add renderer validation for dead source-of-truth paths
• regenerate all per-board workflows

Validation:

• uv run --no-project python ci/render_workflows.py
• uv run --no-project python ci/render_workflows.py --check
• deliberate bogus-path probe fails as expected

Summary by CodeRabbit

• CI Improvements
  • Updated build triggers across supported boards to better match relevant platform and shared build changes.
  • Broadened coverage for shared toolchain, library, package, and build-system updates.
  • Reduced unnecessary workflow runs caused by outdated or overly granular path filters.
  • Added validation to detect stale or invalid CI source paths before workflows are generated.

📝 Walkthrough

Walkthrough

The PR updates generated board workflow path filters to match split build crates, revises CI path source-of-truth files, and adds validation that configured source patterns exist before workflows are rendered.

Changes

CI path filter migration

Layer / File(s)	Summary
Per-board trigger paths .github/workflows/build-*.yml	Push and pull-request filters replace legacy crates/fbuild-build/src/** entries with family-specific build paths and shared build-system crate globs.
CI path sources ci/board_families.json, ci/ci_common_paths.txt	Family and common path definitions now reference the split crate structure and shared build components.
Source path validation ci/render_workflows.py	Rendering validates configured glob patterns against repository files and exits with an error when patterns are stale.

Estimated code review effort: 3 (Moderate) | ~25 minutes
