fix(usage): register emitted feature values

[chrarnoldus]

Summary

Register feature values that production callers already emit so the gateway preserves them in microdollar_usage_metadata.feature_id instead of normalizing them to NULL.

cloud-agent-web is already registered on current main by #4574. This PR adds the remaining observed values and deliberately leaves unknown invalid.

Feature sources

• jetbrains-plugin: set by the JetBrains launcher through KILOCODE_FEATURE in Kilo-Org/kilocode (packages/kilo-jetbrains/backend/src/main/kotlin/ai/kilocode/backend/cli/KiloBackendCliManager.kt).
• daemon: set by the Kilo daemon child environment in Kilo-Org/kilocode (packages/opencode/src/kilocode/daemon/daemon.ts).
• code-review-memory: sent directly by review-memory LLM requests in apps/web/src/lib/code-reviews/review-memory/llm.ts.
• security-remediation: passed as the Cloud Agent createdOnPlatform value by services/security-auto-analysis/src/remediation.ts, then forwarded as KILOCODE_FEATURE.
• github and linear: derived from the Kilo Bot chat adapter name in apps/web/src/lib/bot/agent-runner.ts and passed to spawned Cloud Agent sessions as createdOnPlatform.
• scheduled: used by scheduled Webhook Agent runs in services/webhook-agent-ingest/src/queue-consumer.ts and forwarded by Cloud Agent as KILOCODE_FEATURE.

The Kilo-Org/kilocode sources were checked at commit 982503868326ba72a66419cb5c7d716fe13ea0c7.

Verification

• oxfmt on the changed files
• oxlint on the changed files: 0 warnings, 0 errors
• git diff --check
• Focused Jest was attempted, but the web test global setup could not connect to the configured PostgreSQL test database. The suite failed before assertions ran.

Notes

• unknown remains rejected and has an explicit regression assertion.
• This change registers emitted values verbatim; it does not merge separate producer identities into broader feature buckets.
