fix: remove redundant # prefix from tag display

[victoraraujo105]

Summary

Tags display as ##task instead of #task because the CLI prepends # to tags that already have # from the API.

Root cause

The TaskNotes HTTP API returns tags from Obsidian's metadata cache, which always prepends # to frontmatter tag values (e.g. tags: [task] in YAML becomes ["#task"] in the cache/API response).

lib/utils.js unconditionally prepends another # for display:

// Line 45 - task list display
task.tags.map(tag => colors.highlight(`#${tag}`))
// "#" + "#task" = "##task"

// Line 128 - parsed task display
parsed.tags.map(tag => colors.info(`#${tag}`))

Fix

Remove the redundant # prefix. The API value already includes it:

task.tags.map(tag => colors.highlight(tag))
parsed.tags.map(tag => colors.info(tag))

Reproduction

# Create a task
tn create "Test task today #planning 15m"

# List tasks -- tags show ##task ##planning
tn list

# Check what the API actually returns
curl -s http://localhost:8080/api/tasks | python3 -c "
import sys, json
data = json.load(sys.stdin)
print(data['data']['tasks'][0]['tags'])
"
# Output: ['#task', '#planning']  -- already has #

After fix

Tags: #task #planning
