Extend Discord notifications to push and issue events

[Copilot]

The Discord workflow only handled repository_advisory events and did not notify on normal repo activity. This update broadens event coverage so commits and newly raised issues also produce Discord alerts with event-specific payloads.

• Scope expansion

  • Added workflow triggers for:
    • push (all branches)
    • issues (opened, reopened)
  • Retained existing repository_advisory triggers.

• Event-aware notification payloads

  • Reworked the notification step to branch on github.event_name and build tailored embeds per event type:
    • Advisory: severity/state/CVE/description
    • Push: commit message, short SHA, branch, pusher
    • Issue: issue number/title/state/reporter/description

• Runtime data extraction

  • Switched to reading event data from github.event_path with jq to safely handle differing payload schemas across event types.
  • Preserved webhook guard behavior and HTTP failure handling.

on:
  push:
    branches:
      - '**'
  issues:
    types: [opened, reopened]
  repository_advisory:
    types: [reported, created, published, submitted, reopened]
