feat(code): remove auto-submit from slash commands, fix search

[adboio]

problem

1. when typing to search for a command/skill, the scrolling/filtering does not work
2. commands are not available in the new task view
3. commands always nuke and auto-submit your prompt
4. duplicate skills show up in the list (e.g. one (project)and one (repo-skills-xyz) , they are keyed on name, so multiple skills end up getting highlighted at the same time when searching/filtering and breaking things

changes

1. fixes scroll/filter when typing to search
2. adds commands to the new task view
3. changes to not auto-submit prompts on command selection
4. deduplicates commands/skills by name
   1. no, this is not a very good solution, but it needs more thinking on how we actually want to handle duplicate commands/skills or their names
