chore(deps): bump muxcore to v0.19.0

[thebtf]

Summary

Bump github.com/thebtf/mcp-mux/muxcore from v0.18.2 to v0.19.0.

Why

Groundwork for the upcoming modular-daemon persistence spec (Phase A):

• v0.19.0 enables snapshot infrastructure as a first-class feature in engine facade — daemon.Config.SkipSnapshot: false is hardcoded, so engram automatically gets session-level snapshot/restore after the bump.
• Prerequisite task before we author the formal spec for the modular daemon + muxcore persistence integration.

What changed

Only go.mod / go.sum. No source code changes.

Compatibility check

Diffed muxcore/handler.go and muxcore/engine/engine.go between v0.18.2 and v0.19.0:

• SessionHandler interface — identical. HandleRequest(ctx, ProjectContext, []byte) unchanged.
• ProjectLifecycle, NotificationHandler, NotifierAware — identical.
• engine.runDaemon — now explicitly sets SkipSnapshot: false. SessionHandler takes priority over Handler (consistent with our usage).
• Zero breaking changes; no engram code changes required.

Verification

• go build ./cmd/engram/... — clean
• go test ./cmd/engram/... — pass
• go test ./internal/proxy/... from main working tree — pass

Note: when running go test ./internal/proxy/... from a git worktree, TestResolveProjectSlug_GitRepo fails because it uses git rev-parse --show-toplevel (returns worktree dir) while .engram-project anchor resolves displayName to engram. Pre-existing test fragility in setup, unrelated to this bump. CI runs on a clean checkout and is unaffected.

Rollback

Single-commit chore, trivial git revert if needed.
