* chore(release): wrap changeset version with cross-branch consumed-id ledger When a fix is cherry-picked from main to a release branch (or vice versa), the changeset file ends up on both branches. The release branch's release consumes and deletes its copy, but the cherry-picked copy on main survives the merge back and would be re-applied on the next main release. Introduce a small wrapper around `changeset version` that maintains a per-branch ledger at .changeset/.released/<branch>.txt. Each entry is a consumed changeset id; the file is written only by the branch it is named after, so the records merge across branches without conflicts. Before running `changeset version` the wrapper reads the union of every ledger file, hides matching .changeset/<id>.md files (rename to .md.released), then runs `changeset version` against the remaining set. Newly consumed ids are appended to the current branch's ledger; hidden files are removed afterward (their consumption is already on record elsewhere). On failure the hidden files are restored to keep the working tree clean. * docs: move release-ledger explanation out of AGENTS.md AGENTS.md is for instructions to AI agents working on the codebase, but the cross-branch ledger is release machinery that the maintainer running `pnpm bump` interacts with — agents authoring changesets do not need to know about it. Move the explanation to where someone runs into it: - .changeset/.released/README.md — discovered by anyone exploring the directory. - A short doc-comment header at the top of __utils__/scripts/src/bump.ts pointing readers there. * fix(scripts): harden bump wrapper edge cases from PR review - Use url.pathToFileURL(realpathSync(...)) to compare against import.meta.url so the direct-invocation guard works on Windows paths and through symlinks (Copilot review). - hideReleased() now iterates the changeset directory and filters by the released set instead of iterating the (potentially long) ledger and probing existsSync per entry (Copilot review). - hideReleased() restores already-renamed files if a later rename throws, so a partial failure leaves the .changeset directory in its original state (CodeRabbit review). - Move deleteHidden() into a finally so the .md.released files are cleaned up even if appendReleased() throws after a successful changeset version run (CodeRabbit review). - Add a unit test that forces hideReleased() to fail mid-loop and asserts the rollback.
