# Post-restructure GitHub cleanup (run AFTER pushing the RFC-026 commit).
#
# Prerequisite: re-authenticate `gh` with a valid token before running:
#   gh auth login -h github.com
#
# What this does:
#   1. Pushes the local commit to origin/main
#   2. Deletes stale remote branches (already merged/abandoned)
#   3. (Optional) Creates v1.5.2 tag pointing to the new release commit
#

Application-specific crates (oxios-web, oxios-cli, oxios-telegram)
and the benchmark crate (oxios-bench) are deprecated. Their code is now
part of the \`oxios\` binary as feature-gated modules.

### Breaking changes
- \`oxios-web\`/\`oxios-cli\`/\`oxios-telegram\` crates deprecated (existing
  1.x versions remain available; no further updates)
- Binary \`oxios\` now bundles all channels + HTTP API server
- \`oxios-bench\` removed entirely

### Migration
- Replaces surface/ vs channels/ artificial distinction
- React frontend moved to project root: \`web/\`
- Docker build moved to project root: \`Containerfile\`
- \`rust-embed\` removed — web UI served via runtime GitHub Releases
  download

### Validation
- 1372 tests passing (16 fewer from oxios-bench removal)
- All builds pass (default/cli/telegram/all-features)
- All 8 crates publish to crates.io cleanly

See \`docs/rfc-026-crate-restructuring.md\` for full details." \
