<issue_title>Add buzz schedule command</issue_title>
<issue_description>## Overview

Add a new buzz schedule command that displays a visual representation of how all goal deadlines are distributed throughout a 24-hour day, regardless of when they're actually due. This helps users identify scheduling patterns and bottlenecks in their goal deadlines.

Visualization Design

Use a two-part display:

1. Hourly Density Overview (Top)

A compact vertical bar chart showing goals per hour across the 24-hour day:
HOURLY DENSITY
    ▁     █         █     ▃       ▅
00  06    10        12    15      18      22
├───┼─────┼─────────┼─────┼───────┼───────┼────┤
    1     5         1     2       1       3
2. Detailed Timeline (Bottom)

A vertical timeline listing all goals grouped by their deadline time:
TIMELINE
────────────────────────────────────────────────
06:00 ├─ wake_up
10:30 ├─ exercise, vitamins, breakfast, meditation, journal
12:00 ├─ lunch
15:00 ├─ afternoon_walk, water_check
18:00 ├─ dinner_prep
22:00 ├─ bedtime_routine, reading, evening_review
Implementation Details

Extract time-of-day from all goal deadlines (ignoring the date)

Group goals by exact time

Count goals per hour for density chart

Sort chronologically through the day

Display using ASCII characters that work well without colors

Benefits

Quick visual scan of busiest hours

Identify scheduling imbalances and bottlenecks

Understand goal distribution patterns

Works well in terminals with colors disabled</issue_description>

Comments on the Issue (you are @copilot in this section)
@narthur @coderabbitai How might this work? What might it look like? Is this feasible with just ASCII output? @narthur @coderabbitai The goal for this command would be to see how all goal deadlines are distributed throughout a day as if they were all due today, regardless of whether they are actually due today or not. So I'm less concerned about color-coding for urgency and more about making clear which goals are due at which times. Also it may be relatively common for many goals to have due times at the exact same time, for example 5 different goals all due at 10:30am. @narthur @coderabbitai Option A is interesting. Could Option A be combined with a second compact visualization above it that gives a visual overview of the density of deadlines for each hour of the day? Maybe horizontally? Perhaps using a color gradient? So the option A timeline wouldn't be forced to expand to keep everything in scale when multiple goals are due at the same time, since the horizontal density graph above it would serve that function. @narthur @coderabbitai Let's go with version 2 so that it'll work well even when the user disables colors. Let's update this issue's description and title with our new plan. @narthur @coderabbitai Using `buzz clock` as the command for this feels potentially misleading. What are some better options for this command's name?

Note

Introduces a new CLI command to visualize goal deadline distribution across a 24‑hour day.

Adds buzz schedule with two ASCII views: displayHourlyDensity (per-hour bar chart with capped counts) and displayTimeline (chronological groups by exact HH:MM)
Implements time extraction/grouping via extractTimeSlots and wires command into main (help text, command switch)
Adds comprehensive tests for slot extraction and both visualizations; updates README with usage and examples
Minor: import sort; add .tool-versions (Go 1.24.12)

Ensure goal.Losedate is converted to local time when extracting the hour and minute. Previously the code used time.Unix(goal.Losedate, 0) which returns a UTC-based Time value; converting to local time with In(time.Local) yields the correct local hour and minute values. This prevents incorrect slot assignment caused by timezone differences between stored timestamps and the server's local timezone.

Add TestTimelineFormatting to exercise displayTimeline formatting behavior for hours/minutes and goal joining. The new tests cover zero-padded times (including midnight, noon, and late-night), and multiple-goal joining cases to ensure output matches expected strings. Also import fmt and strings for test helpers. Also add .tool-versions pin for Go 1.24.12.

Update hour-count rendering to cap large values with a trailing plus sign and to write label runes into the buffer using a bounds-checked loop. - Change cap behavior from "99" to "99+" so the UI indicates overflow rather than truncating the value. - Replace ad-hoc single/double digit placement with a for-loop that writes each rune and stops at the buffer end to prevent index overflow. This simplifies the placement logic and prevents accidental truncation or out-of-bounds writes when labels exceed available space.

main.go

schedule_test.go

Align axis markers to the actual label positions instead of printing a fixed ASCII axis string. Build a rune buffer sized to the output, place '┼' markers at computed positions from labelHours, and fill horizontal segments '─' between the first and last marker. Skip markers that would fall outside the buffer. This makes the axis adapt to label positions and prevents misaligned or truncated markers when labelHours change.

Remove the redundant shouldPass boolean from schedule_test.go. The tests already infer success from assertions and the table-driven cases only provide name and hourCounts, so keeping shouldPass added noise and unused fields. Simplify the test table to improve readability and reduce maintenance overhead.
