🔧 chore(release): prepare v1.6.0-rc.1 changelog entry

[scttbnsn]

Promotes the [Unreleased] block to [1.6.0-rc.1] - 2026-08-05 with a release-candidate intro paragraph covering the full v1.6 roadmap (#149, #151, #152, #153, #148, #150), and adds a fresh empty [Unreleased] block above it, per RELEASING.md step 5.

Also fixes two spacing glitches merge resolutions left in the block: a missing blank line before ### Tests and a doubled blank line before [1.5.2].

Verified locally:

• node scripts/extract-changelog-entry.mjs --version v1.6.0-rc.1 extracts a non-empty entry (the release-cut validation)
• node --test scripts/release-metadata.test.mjs passes (stable metadata stays 1.5.2 until GA promotion)
• govulncheck ./...: zero reachable vulnerabilities (pre-tag gate 3)

Next steps after this merges: sync main from dev/v1.6, cut v1.6.0-rc.1 via the release-cut workflow, then run the new tri-tool conformance matrix against the published rc.1 image as the pre-GA gate.

Changelog

• 🐛 Fixed TestRequestIDGeneratorBatchesEntropyReads flakiness by stopping the background refill goroutine before deterministic pool refilling.
• ✨ Added the v1.6.0-rc.1 changelog entry and release-candidate introduction.
• 🔧 Added a new empty [Unreleased] section and corrected changelog spacing.
• 🔧 Verified changelog extraction, release metadata tests, and govulncheck ./....

Concerns

• Sync main before cutting v1.6.0-rc.1.
• Run the tri-tool conformance matrix.
• Confirm the race-detector verification covers 200 test runs.

📝 Walkthrough

Walkthrough

The test now closes the request ID generator before calling refillSync. This stops the background refill goroutine before the test checks the deterministic entropy fill count. Deferred cleanup was replaced with immediate closure.
