…nicode codepoint escape for the infinity symbol to ensure

consistent encoding across environments Change number formatting
from right-aligned to left-aligned in the 2-character badge field
so small counts render more predictably within the fixed-width slot.

This improves visual consistency of count badges and avoids encodingissues with literal symbols source files.

When rendering the hour axis, use a downward-only tick (┴) for hours
that have zero counts and a full cross (┼) for hours with counts.
This makes the axis visually reflect whether an hour extends down
(from counts) or only up, improving clarity of the chart.

Use a strings.Builder to construct the hour label line and apply
ANSI gray color to hours that have zero counts. This replaces the
previous fixed-width rune buffer approach and simplifies label
assembly while visually de-emphasizing inactive hours. Keep spacing
and output layout unchanged.

Improve timeline printing by wrapping long goal lists to fit the
terminal width and indenting wrapped lines for readability.

- Preserve original "HH:MM ├─ " prefix and compute its visual width.
- Read COLUMNS env var (fallback to 80) to determine available width.
- Split goals on commas and assemble lines so they don't exceed width,
  printing a new indented continuation line when needed.
- Use a vertical continuation marker and consistent indentation to
  align wrapped content with the goals column.
- Add fallbacks and minimal safety width to avoid pathological layouts.

This prevents overflowing long goal lists and improves clarity on narrow
terminals.

Refactor goal-wrapping logic to correctly split and wrap long
comma-separated goal lists across multiple output lines.

- Move goals splitting and line builder setup out of inner loop for
  clearer control flow.
- Iterate over goals without relying on index; compute separator
  based on current line content.
- When a goal does not fit, print current line, start a new wrapped
  line prefixed with a vertical continuation marker, and write the
  overflowing goal to the new line.
- Ensure a trailing comma is added when wrapping to indicate there
  are more goals on the next line.

These changes fix incorrect separator handling and ensure wrapped
lines maintain readable indentation and punctuation.

Add ANSI color sequences to the timeline printer to improve visual
clarity. Time labels now appear in cyan and the tree/continuation
characters (├─ and │) appear in gray. Wrapped continuation lines
also include the colored vertical separator so wrapped text keeps the
same visual structure.

This change updates prefix construction and the continuation-line
indent so widths remain correct while inserting color escape codes.

Update hour label and timeline rendering to avoid emitting ANSI
color sequences when colors are disabled. Detect the terminal color
profile and only apply gray/cyan/reset escape codes if a non-ASCII
color profile is in use.

Key changes:
- Add colorProfile detection before building hour labels and skip
  dimming (gray) when colors are disabled.
- Guard time/tree/reset color variables for timeline output behind
  the same colorProfile check to prevent bare escape codes when
  --no-color is used.

This prevents visible raw ANSI sequences from appearing in
environments where colors are turned off and keeps visual dimming
when colors are available.
