Update Commit Composer Telemetry

[justinrobots]

Description

Add new telemetry events for Commit Composer View:

• when CC View is opened with compose action (compose working directory changes)
  • where it was opened from (e.g., Home View, graph, commit details, command palette, etc.)
  • if all changes were staged, unstaged, or a mix
    - [ ] when CC View is opened with recompose action (recompose existing commits)- [ ] where it was opened from (branch label, multi-select commits, etc.)- [ ] how many commits existed at the start? (not included in first release)
• when unstaged workng changes are added to the draft commit
• when a commit message is generated by AI in CC View
• when a commit message is re-generated by AI in CC View
• when custom instructions are added to composition actions
• when the model is changed before composition action
• when a composition action is completed (diffs sent to AI and draft commits are returned)
  • if the action was compose or recompose
  • how many draft commits were returned?
• when a CC flow is finished:
  • when "finish" is clicked
  • when commits are actually made manually without AI composition
  • when commits are actually made that have been composed by AI
• when a CC flow is cancelled
• when changes are reset completely
• when a specific change is undone

CC telemetry session package:

• Custom Instructions setting version (string length)
• Model (full object we use in AI telemetry)
• Custom Instructions (as hash and length)
• Counts for files, hunks and lines
• Counts of final commits
• Counts per final commit (?, ping GKD)
