Promote fleet-unanimous features.* and issueDiscoveryPolicy to global.gittensory.yml (VPS)

[JSONbored]

Context

All 3 gate repos independently declare identical features: {unifiedComment: true, safety: true, reputation: true, rag: true} and issueDiscoveryPolicy: discouraged; global.gittensory.yml has neither. issueDiscoveryPolicy staleness is fully confirmed (parser default is "neutral", focus-manifest.ts:3078). The features: half is lower-confidence — these 4 keys fall back to a GITTENSORY_REVIEW_REPOS env allowlist when unset (src/review/feature-activation.ts), which requires checking the dedicated server's .env (never committed, not inspectable from this repo audit alone).

Requirements

• Direct edit to the private dedicated-server config, not a GitHub PR.
• Check the GITTENSORY_REVIEW_REPOS env value on edge-nl-01 before touching the features: block — if it doesn't already list all 3 repos, the per-repo features: declarations are load-bearing and must NOT be removed (only added to global as a belt-and-suspenders default).

Deliverables

• Add issueDiscoveryPolicy: discouraged to global.gittensory.yml — safe with certainty (per-repo always wins in the merge order, so this is a no-op for the 3 existing repos, only sets the correct default for a future repo).
• Check GITTENSORY_REVIEW_REPOS on edge-nl-01. If it already lists all 3 repos, promote features: to global and optionally drop the per-repo redundancy. If not, add to global anyway (safe, per-repo still wins) but leave the per-repo blocks in place.

Expected Outcome

issueDiscoveryPolicy gets a correct global default. The features: promotion is done with confirmed knowledge of whether the per-repo declarations are load-bearing, not guessed.

JSO-3774

[JSONbored]

Applied directly to global.gittensory.yml on the dedicated server, 2026-07-12 (same edit/backup as #5274). Added issueDiscoveryPolicy: discouraged (safe/certain — parser default is "neutral", per-repo always wins). Checked GITTENSORY_REVIEW_REPOS env on edge-nl-01 — it already lists all 3 repos, so also promoted features: {unifiedComment, safety, reputation, rag: true} to global as a belt-and-suspenders default; left the per-repo declarations in place rather than removing them.
