Sync upstream, migrate org refs, introduce go.work workspace & example modules

[intel352]

Summary
This PR syncs changes from upstream (ctl/main) into this fork and applies a comprehensive migration to the GoCodeAlone organization namespace.

Key Changes

• Migrated import paths: CrisisTextLine/modular -> GoCodeAlone/modular across core, modules, CLI, and examples
• Added full go.work workspace enumerating core, cmd/modcli, all modules, and 27 examples
• Added new examples (auth-demo, cache-demo, eventbus-demo, jsonschema-demo, letsencrypt-demo, scheduler-demo) with canonical module paths
• Introduced go.work.sum (generated) for reproducible workspace builds
• Normalized example go.mod module directives to github.com/GoCodeAlone/modular/examples/
• Updated reverseproxy & eventbus docs to reflect new import paths
• Bumped testify to v1.11.1 and hashicorp/go-uuid to v1.0.3 where needed (indirect tidy)
• Removed remaining legacy path references in code (only git remote metadata still references upstream)

Rationale
Adopting go.work unifies intra-repo dependency resolution without maintaining pinned pseudo-versions between internal modules, simplifying local development and reducing merge friction.

Verification

• Ran full lint & test task: all core, module, CLI tests pass; examples build (most have no tests by design)
• Built each example individually to verify workspace resolution
• Grep confirms no remaining CrisisTextLine references in tracked source files

Follow-ups (Optional)

• Add CI guard ensuring every examples/* with go.mod appears in go.work
• Evaluate release workflow adjustments now that module version pins are removed locally
• Consider pruning explicit requires on core module where workspace resolution suffices (post-release decision)

Let me know if you’d like any of the optional follow-ups included in this PR.

Comments suppressed due to low confidence (2)

modules/eventbus/memory.go:1

• [nitpick] This comment is excessively detailed for inline code documentation. Consider moving this operational guidance to the module's README.md or creating a separate documentation file. Inline comments should be concise and focus on the immediate implementation details.

modules/eventbus/memory.go:1

• [nitpick] While this documentation provides valuable design context, it's extremely verbose for a struct comment. Consider condensing this to the essential information and moving the detailed rationale to a design document or the module's README.
