v0.6.0 — Notification overhaul

Highlights

Major overhaul of Slack and Discord notifications for runtime errors, monitors, new endpoints, log patterns, and scheduled reports — denser, clearer, less wasted vertical space, and more actionable.

Slack alerts

• Severity color bar via attachments wrapper — red/orange/amber/blue/green/slate applied consistently across all alert types
• Compact titles — {emoji} *{label}* · {errorType} in {project} (no more triple-duplicated error headers)
• Top stack frame inlined in the body for file/line context at a glance
• Secondary action button — View trace appears alongside 🔍 Investigate when a traceId is present, jumping into Log Explorer filtered by trace_id
• Single context block (was up to three), empty fields dropped instead of rendering as empty backticks
• First seen now shows compact relative + absolute time (e.g. 3m ago · Apr 14 4:17 PM)
• Field labels standardized: Environment / Route / Rate / Runtime / Trace
• Monitor alert: passive 🤖 Alert triggered for X → active 🚨 Monitor alerting: X; resolved state gets green bar + clickable title
• New endpoints: proper singular/plural, redundant body prose removed
• Log-volume rate change: signed change (+42% / -18%), amber on spike / blue on drop
• Report: merged context blocks, terse image titles, explicit Open report button

Discord alerts

• Per-severity embed colors matching Slack palette
• Monitor content and titles aligned with Slack wording
• Removed redundant body intros on log-pattern and rate-change embeds
• New-endpoint plural fixed

Chart rendering fix

• ECharts bars rendered as a fused "square blob" due to showBackground painting empty buckets — removed, added barCategoryGap: 30%, barMaxWidth: 10, and rounded borderRadius so columns read as distinct rounded bars

Incidental fixes

• Trace viewer: orphan spans whose parent isn't in the current batch are normalized to roots instead of being silently dropped
• Span timing bar chart: guard against non-finite maxDuration when all bars share the same start
