Optional Texio trial for Markdown section tasks alongside ecotokens

[JonghunYu]

Your hooks and native-tool filtering already reduce what enters model context. Would an explicitly selected Texio recipe help on tasks limited to a named Markdown section, before filtering is applied? I am suggesting a small optional companion-tool trial, not automatic replacement of reads or an unmeasured addition to the gain dashboard. Compare the existing ecotokens workflow against the same setup plus Texio on a real README task, retaining surrounding context when required. A native solution or no additional tool may be cheaper.

I maintain Texio, an MIT-licensed early-preview CLI. A minimal disposable-file trial with Texio 0.1.3 installed is:

texio headings README.md --json
texio section README.md Installation
texio replace README.md --section Installation --text 'New installation instructions.' --dry-run

The preview does not write. Replacement covers the entire selected body, including nested subsections; preserve any content you want to retain. Missing or ambiguous headings cause refusal. Installation and platform limits.

There are no measured token savings for this integration yet. Measure total task input/output (including cached tokens where available), retries, correctness and setup cost against your normal tools. Would a small comparison be useful? I can help prepare it before any implementation PR.
