chore(deps): plan Vite 8.x upgrade

[oaslananka]

Goal

Plan the Vite 8.x major dependency upgrade without bundling it into unrelated maintenance PRs.

Current state

• Current version: ^6.5.0\ (managed by Renovate)
• Target version: ^8.0.0\
• Depends on vitepress supporting Vite 8.x

Upstream status (verified 2026-08-02)

• Stable VitePress is 1.6.4 and still depends on Vite ^5.4.14.
• The VitePress next channel is 2.0.0-alpha.18 and depends on Vite ^8.1.3.
• The stable documentation toolchain therefore does not yet support Vite 8. The upgrade remains intentionally blocked; an alpha VitePress migration is out of scope for routine dependency maintenance.

Risk

• Breaking API changes in Vite 8.x
• vitepress compatibility with Vite 8.x
• Build/dev bundle changes
• CI matrix compatibility
• No runtime impact (Vite is dev-only, not shipped in VSIX)

Validation required

• \pnpm install --frozen-lockfile\
• \pnpm run typecheck\
• \pnpm run lint\
• \pnpm run test\
• \pnpm run build\
• \pnpm run check\
• CI matrix (all platforms)

Notes

• Blocked on a stable VitePress release compatible with Vite 8.x.
• Do not approve the Renovate vite-8.x branch while compatibility requires an alpha VitePress line.
• Re-verify the stable VitePress dependency range before creating the migration PR.
• Requires Renovate Dashboard approval only after the blocker is cleared.

Out of scope

• Unrelated dependency upgrades
• Release/publish changes
• Weakening CI or security checks
• Changing KiCad support policy
• Moving MCP server implementation into this repo

Acceptance criteria

• Migration notes reviewed
• Minimal code changes identified
• Full validation green
• Rollback path documented

Post-maintenance-session update — 2026-06-17

No change to blocking state

This maintenance session merged 8 safe patch/minor dependency PRs. No Vite-related changes were shipped.

Current blocker

• Vite 8.x remains blocked on vitepress compatibility. VitePress 1.6.x pins Vite ^6.0.0\ and is not compatible with Vite 8.x.
• No vitepress release supporting Vite 8.x is available yet.
• Dependency Dashboard Dependency Dashboard #244 lists this as \Pending Approval — blocked.

Validation required (once unblocked)

• \pnpm install --frozen-lockfile\
• \pnpm run typecheck\
• \pnpm run lint\
• \pnpm run test\
• \pnpm run build\
• \pnpm run check\
• Full CI matrix (all platforms)

Upgrade plan documented in PR #444 (Planned Major Upgrades → Vite 8): migration notes, minimal code changes identified (the vite: 6.4.3 pnpm-workspace.yaml override that drives the VitePress docs build; no app/runtime imports), validation gate, and rollback path. Remains blocked on a stable VitePress 2.x with Vite 8 support — keep renovate/vite-8.x unapproved on the dashboard (#244). This issue stays open until the execution PR lands.
