feat: issue channel announcements (open / assign / close)

[shubham5080]

Summary

• Post new issues to the same discord.pr_open_channels map used for PRs when notifications.issue_opened is enabled (default off).
• Keep Opened by on the message always; show Assigned to: None until assignment, then update to the contributor.
• On close, edit the same message to Closed and add Closed by @who, without dropping opened/assigned lines.
• Track announcements in SQLite (issue_channel_announcements); enrich issue payloads with assignee / closed_by.

Test plan

• pytest tests/test_notifications.py (issue channel cases + full file)
• Enable issue_opened: true in org remote gitcord.yaml, rebuild bots
• Open an issue in a mapped repo → channel shows Opened by + Assigned to: None
• Assign the issue → message edits Assigned to
• Close the issue → message shows Closed by, keeps prior lines

Walkthrough

Adds configurable Discord notifications for opened issues. The change stores issue announcements, updates them when issues are assigned or closed, extends issue payload data, wires new events into the orchestrator, and adds coverage for notification and storage behavior.

Changes

Issue channel notifications

Layer / File(s)	Summary
Notification contracts and issue data src/ghdcbot/config/models.py, src/ghdcbot/adapters/github/rest.py, config/*.yaml, config/examples/*.yaml, tests/test_notifications.py	Adds issue_opened and lifecycle settings. Issue payloads now include assignee and closer data. Configuration examples enable or document the new settings.
Announcement storage and rendering src/ghdcbot/adapters/storage/sqlite.py, src/ghdcbot/engine/notifications.py	Adds SQLite persistence for issue announcements. New helpers build open and closed messages. Notification functions post and update tracked announcements.
Event wiring and validation src/ghdcbot/engine/orchestrator.py, tests/test_notifications.py	Routes issue-opened, assigned, and closed events to the new notification functions. Tests cover posting, lifecycle edits, disabled notifications, untracked issues, SQLite round trips, and payload extraction.

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Feature

Merge Risk: 🟡 Moderate · up to 26969

Issue announcements can lose closure attribution, and crafted issue titles may notify unintended Discord users or roles. These notification behaviors should be corrected before enabling the feature broadly.

In `@config/examples/remote-gitcord-stability-nexus.yaml`:
- Line 105: Extend _sanitize_discord_pr_title to neutralize Discord user and
role mention syntax in issue titles, in addition to `@everyone` and `@here`, before
_build_issue_channel_message passes the title to create_message. Preserve
intended author and assignee mentions by limiting the change to sanitized
issue-title content rather than disabling allowed mentions globally.

In `@src/ghdcbot/engine/notifications.py`:
- Line 799: Update _sanitize_discord_pr_title so issue titles neutralize
structured Discord user, role, and channel mention tokens in addition to
`@everyone` and `@here` before assignment to issue_title; alternatively disable
parsed mentions for the resulting message while explicitly preserving only
trusted mentions.
- Around line 630-637: Update the issue_assigned branch in the notification
updater to return before assignment edits when status is "closed", preserving
existing handling for open issues. Add a regression test covering a closed
announcement and verifying that an issue_assigned event does not alter its
closed-by display.
