Refactor generate-release.sh for .speckit subfolder structure

[mkellerman]

• Add --package flag to create release packages (claude, gemini, copilot)
• Add --cleanup flag to remove generated folders and zip files
• Add SPECKIT_DIR variable for configurable directory naming
• Implement update_speckit_path() function with array-based folder mapping
• Fix macOS BSD sed compatibility (remove \b word boundaries)
• Update file copying to handle hidden directories with sdd-base-package/.
• Replace hardcoded .speckit references with $SPECKIT_DIR variable
• Consolidate path updates for memory/, scripts/, and templates/ folders

Proposal fix for issue #38

I would consider additional changes:
move all agentic commands in their own subfolder, ex: .claude/commands/speckit/* as these might collide with commands the user uses himself or from other projects.

Hi @mkellerman,
Could you please add documentation explaining how the folder structure configuration works with the new .speckit subfolder structure? Having some usage examples or details in the README would be very helpful for contributors and users.
Thanks!

@localden I would love to resolve conflicts, and complete this PR, but only if there is a chance that this might get merged in. So some kind of 👍 would let me know to continue working on this.

@mkellerman thank you for the contribution - I refactored things a bit differently in the latest release. Check them out and see if there is anything that stands out or that I missed.
