feat(issue-list): redesign table to match Sentry web UI

[BYK]

Redesign the sentry issue list table to match the Sentry web UI issue stream layout with better information density and visual clarity.

Column Layout

SHORT ID | ISSUE | SEEN | AGE | TREND | EVENTS | USERS | TRIAGE

Changes

Sparkline trend graphs

New sparkline module using 8-level Unicode block characters (▁▂▃▄▅▆▇█) with bucket-averaging downsample. Requests groupStatsPeriod=auto from the API.

2-line default rows

• ISSUE: bold title + muted subtitle (metadata value/type)
• TREND: sparkline on line 1, substatus label on line 2 (New, Ongoing, Regressed, Escalating)
• SHORT ID: linked ID + alias shorthand (multi-project mode)

--compact flag

Single-line condensed rows: title only (truncated with …), sparkline+substatus on same line, alias as suffix.

TRIAGE column

Composite score blending priority and Seer fixability: impact × 0.6 + fixability × 0.4. Colored by tier (green ≥67%, yellow 34–66%, red ≤33%).

Text table improvements

• Row separators (dimmed horizontal dividers)
• Multi-line cell width fix: string-width sums across newlines instead of taking the max line width — added cellVisualWidth() helper

Removed/renamed columns

LEVEL, ALIAS (merged into SHORT ID), ASSIGNEE, PRIORITY (→ TRIAGE). COUNT → EVENTS.

Multi-line cell values break plain markdown table output

Medium Severity

The new 2-line cell formatters (formatIssueCell, formatIdCell, formatTrendCell) embed literal \n in cell values for the default (non-compact) layout. In plain output mode (isPlainOutput()), buildMarkdownTable renders each row as a single | ... | ... | line via stripColorTags(c.value(item)). The embedded \n splits what was meant to be a single table row into multiple broken lines, producing invalid CommonMark table syntax. This affects piped output, CI, NO_COLOR, and SENTRY_PLAIN_OUTPUT environments.
