v1.3.24 — Measured optimization worked example

I added a runnable measured optimization example using the existing Pocket Ledger reconstruction. The protocol was frozen before implementation; literal correctness oracles, all raw paired timings, runtime/workload/source identities and executable evidence checks are retained.

The single-pass Unicode candidate passes the selected behavior tests but does not demonstrate an overall speed benefit. Typical and stress medians were higher in both final processes, while small-input medians disagreed. I retained the original implementation and the unsuccessful candidate as a teaching example. Results cover only the recorded synthetic workloads and Windows Node runtime; no universal speed or memory claim.

The companion's performance guide now explains bounded experiments, equivalent work and output consumption, precise resource metrics, failed/inconclusive outcomes and complete raw-sample review. No new dependency, model benchmark or machine-sensitive CI timing gate.

Validation: five focused source/package regressions; full existing public CI across Node20/22/24 on Linux, Windows and macOS; source/extracted package, manifest, links/privacy, genuine skill validators, eight isolated install configurations and eight exact-ZIP upgrades. Windows source/package each487/487 with0 skips; Linux retains3 casing-related skips. Local full suites remained unrun after denied junction preflights, never treated as passes. Authorship and substantive review were same-agent and source-exposed, not independent.

The installer, updater, consent/alias/integration/recovery contracts, historical fixtures and README support links remain intact. Installed-skill maintenance preserves the selected settings and backups. Existing host sessions may need a refresh to load changed guidance.

The first tag run had one Windows Node22 CLI-capture timeout in the unchanged artifact harness (486 passes,1 failure; that job's package suite unrun). One retry of that job with identical code/tests/three-second timeout passed source and extracted package487/487 with0 skips and the same ZIP digest. The original failure is retained; its root cause remains unknown. A passing retry does not establish a harness fix. All other tag jobs passed on their first attempts; no benchmark was rerun.

Release ZIP:2,220,798 bytes; SHA256 fe6c890ae0b428af92ea0db0f90c7e81e2f5654550739baab68ef971012c56da. This exact local/Windows artifact is published; other platform builders may produce different compressed ZIP bytes while verifying the same manifest/payload.
