Description

Implement dynamic completion support that queries the backlog system for context-aware suggestions.

Dynamic completions should include:

Task IDs when relevant (e.g., 'backlog task edit [TAB]' shows actual task IDs)
Status values from config (e.g., '--status [TAB]' shows configured statuses)
Priority values (high, medium, low)
Label values from existing tasks
Assignee values from existing tasks

This requires the CLI to provide a completion helper command that shells can invoke to get dynamic values.

Acceptance Criteria

[x] #1 CLI provides completion helper command (e.g., 'backlog __complete')
[x] #2 Task IDs complete when editing tasks
[x] #3 Status values complete from actual config
[x] #4 Priority values complete correctly
[x] #5 Labels complete from existing tasks
[x] #6 Assignees complete from existing tasks
[x] #7 Dynamic completions work in bash, zsh, and fish

Implementation Notes

Dynamic completions are already implemented through the completion helper system:

getTaskIds(): Returns actual task IDs from Core API
getStatuses(): Returns configured status values from config
getPriorities(): Returns high/medium/low
getLabels(): Extracts unique labels from all tasks
getAssignees(): Extracts unique assignees from all tasks
getDocumentIds(): Returns actual document IDs from Core API

The completion helper automatically provides these dynamic completions based on context:

Task IDs when completing commands like backlog task edit <TAB>
Status values when completing --status <TAB>
Priority values when completing --priority <TAB>
Labels when completing --labels <TAB>
Assignees when completing --assignee <TAB>

All three shell scripts (bash, zsh, fish) call the backlog completion __complete command which uses these data providers to return context-aware, dynamic completions.
