Add timers CLI command to ottoctl

[Copilot]

Implements a new timers command for the ottoctl CLI to query timer/ticker information from the Otto server's existing /api/timers endpoint.

Changes

• cmd/ottoctl/cmd_timers.go: New Cobra command following the pattern of stats and stations commands
• client/client.go: Added GetTimers() method to fetch []utils.TickerInfo from /api/timers
• cmd/ottoctl/cmd_root.go: Registered timersCmd with root command
• cmd/ottoctl/cmd_timers_test.go: Test coverage for success, empty response, and error cases
• cmd/ottoctl/testdata/timers.json: Test fixture data

Usage

# Query timers from server
./ottoctl timers --server http://localhost:8011

# Output (JSON formatted)
[
  {
    "name": "heartbeat",
    "last_tick": "2026-01-04T16:40:00Z",
    "ticks": 120,
    "active": true
  }
]

Additional Fixes

• cmd/ottoctl/ottoctl/Makefile: Corrected go build flag order (-o before target)
• .gitignore: Added cmd/ottoctl/ottoctl/ottoctl to exclude binary from version control

The error message formatting is inconsistent with the pattern on line 30. The error should include a newline character for consistency. Consider changing fmt.Fprintf(errOutput, "%s", err) to fmt.Fprintf(errOutput, "%v\n", err) or fmt.Fprintf(errOutput, "Error marshaling JSON: %v\n", err) to match the format used on line 30.

Suggested change

	fmt.Fprintf(errOutput, "%s", err)
	fmt.Fprintf(errOutput, "%v\n", err)
