Bump hotpath Version

Bump the hotpath version number in every place it appears. The user provides the new version (e.g. 0.25.0); if only major.minor is given, assume patch 0.

Three formats are used:

• Exact version (X.Y.Z, e.g. 0.25.0) - all Cargo.toml entries
• Major.minor only (X.Y, e.g. 0.25) - crate version references
• Release tag (vX.Y.Z, e.g. v0.25.0) - hotpath-relay.yml pins

1. Cargo.toml files - exact version X.Y.Z

Update the version field in the [package] section of each crate:

• crates/hotpath/Cargo.toml
• crates/hotpath-macros/Cargo.toml
• crates/hotpath-meta/Cargo.toml
• crates/hotpath-macros-meta/Cargo.toml
• crates/hotpath-drain/Cargo.toml
• crates/hotpath-drain-meta/Cargo.toml

Update the version in the six [workspace.dependencies] entries in the root Cargo.toml:

hotpath-macros = { path = "./crates/hotpath-macros", version = "X.Y.Z" }
hotpath-drain = { path = "./crates/hotpath-drain", version = "X.Y.Z" }
hotpath = { path = "./crates/hotpath", version = "X.Y.Z" }
hotpath-meta = { path = "./crates/hotpath-meta", version = "X.Y.Z" }
hotpath-macros-meta = { path = "./crates/hotpath-macros-meta", version = "X.Y.Z" }
hotpath-drain-meta = { path = "./crates/hotpath-drain-meta", version = "X.Y.Z" }

All six crates always share the same version; never bump one without the others. This matters for the drain crates even when their code is unchanged: published hotpath-drain depends on hotpath-meta, so a drain left on an older release keeps pulling a stale hotpath-meta copy into downstream lockfiles (and splits meta profiling across two versions). All six are published together via just cargo-publish, which lists them in dependency order.

2. Other references - major.minor X.Y

• ../hotpath-backend/src/config/middleware.rs (separate repo, sibling directory):

  ("{{HOTPATH_VERSION}}", "X.Y"),
  

• skills/hotpath_init/SKILL.md - every version occurrence (hotpath = "X.Y", hotpath = { version = "X.Y", ... })

• README.md - every version occurrence (cargo install hotpath --version '^X.Y', hotpath = "X.Y")

3. Relay release tag - vX.Y.Z

Adopters pin the reusable relay workflow to the release tag, so these point at the tag this release creates:

• ../hotpath-backend/src/config/middleware.rs:

  ("{{HOTPATH_RELEASE_TAG}}", "vX.Y.Z"),
  

• skills/hotpath_init_ci_forks/SKILL.md - every vX.Y.Z occurrence (the hotpath-relay.yml@vX.Y.Z pin and the pinning instructions)

• .github/workflows/hotpath-relay.yml - the hotpath-relay.yml@vX.Y.Z pin in the usage comment at the top

Leave .github/workflows/cloud-random-benchmark-relay.yml on @main: it tests the relay on the default branch.

4. Verify

Search for stragglers with the old version, excluding lockfiles, target dirs, and third-party code:

rg -n 'OLD_X\.OLD_Y' Cargo.toml README.md skills/ crates/hotpath/Cargo.toml crates/hotpath-macros/Cargo.toml crates/hotpath-meta/Cargo.toml crates/hotpath-macros-meta/Cargo.toml crates/hotpath-drain/Cargo.toml crates/hotpath-drain-meta/Cargo.toml
rg -n 'OLD_X\.OLD_Y' ../hotpath-backend/src/config/middleware.rs .github/workflows/hotpath-relay.yml

Ignore matches that are not hotpath version references (other dependencies may coincidentally share the number). Then run cargo check so Cargo.lock picks up the new versions.

Rules

• Do not commit; leave changes for the user to review.
• Do not bump versions of test crates or any other dependency versions.
