Fix StoonMesh contact and add Winnipeg MeshCore

[n30nex]

Community directory updates

Closes #94
Closes #95

• Replace StoonMesh's unaffiliated Mesh Saskatchewan Telegram link with the submitted StoonMesh Discord invite.
• Add Winnipeg MeshCore in Manitoba as Forming, with its website and Matrix room. No local radio override was supplied, so the entry inherits the existing Canada defaults.
• Regenerate the English and French national, Saskatchewan, and Manitoba pages. Directory totals are now 25 listings: 23 active and 2 forming.
• Include Winnipeg in text and nearby-community search using the existing Winnipeg region reference. This is an approximate search point, not a claimed radio location or coverage boundary.
• Support Matrix contact labels in the existing schema and generator; no new dependency or separate contact system.

Verification

• All GitHub checks pass for commit a62bc81: validation, Lighthouse, and the full browser/accessibility suite (620 passed, 34 skipped). The stale 24-listing browser assertions now read the community data.

• The new Discord invite resolves to StoonMesh. Winnipeg's website returned HTTP 200 and its public Matrix alias resolved on September 24, 2026.

• Community/content validation and all 16 Python content tests passed.

• All 16 focused directory/content regression tests passed.

• All 172 Node content/editor checks passed across the final runs (160 core checks plus 12 broker-helper checks run separately after a Windows Git Bash timeout).

• Strict bilingual build passed: 129 pages and 13,314 internal references checked.

• English/French directory-to-detail journeys passed across six desktop/mobile browser configurations. Firefox passed both journeys when rerun serially after a browser-context cleanup error in the first parallel run.

• Generated files were rechecked and the patch passes whitespace checks.

This PR is based on current main and is independent of the open preset update in #93. It does not merge, deploy, change radio settings, or modify MQTT accounts. Both issues will close automatically when this PR is merged.

Fixed the browser check failure in a62bc8139b559d0ffd639d76c4a403d33e7fb483.

The nearby-community tests still expected 24 cards after “Show all” and “Clear.” Adding Winnipeg correctly raises the total to 25. Both assertions now use the checked-in community data, so they remain valid when listings change. No site behavior or community entries were changed by this correction.

All 54 local feedback browser tests passed, including both affected English/French journeys in all six browser configurations.

The fresh GitHub run is now fully green: validation, Lighthouse, and browser/accessibility checks passed. The full browser suite finished with 620 passed, 34 skipped. The PR remains open for review and still closes #94 and #95 when merged.
