Renovate's bun manager already reads "packageManager": "bun@x.y.z" in app/package.json as the npm package bun (also in the subfolder: no unknown-engines skip in the run below). The extra regex manager read the same line a second time, so two dependencies edited it. This drops the regex manager; the Bun group matches bun already, so its grouping was right and stays so.

Test

A Renovate 44.211.0 lookup run (--platform=local --dry-run=lookup) on a copy of the Bun-related files with Bun pinned back to 1.3.0, checking the branch of every Bun update and that packageManager is read by one manager only (the check of firsttris/fernsicht#18 and firsttris/stellwerk#26, extended by the second point).

Before (origin/main):

bun app/package.json: bun 1.3.0 -> renovate/bun
regex app/package.json: bun 1.3.0 -> renovate/bun
FAIL: packageManager of app/package.json read by bun and regex
FAIL: 1 problem(s)
exit 1

After (this branch):

bun app/package.json: bun 1.3.0 -> renovate/bun
ok: every Bun update in renovate/bun, packageManager read once
exit 0

renovate-config-validator --strict (Renovate 44.211.0): Config validated successfully.

Toolbox and Debian setup install the Bun of packageManager

packaging/toolbox.sh and the Debian lines of docs/development.md installed the newest Bun (curl … | bash), not the one CI runs. They now read the version from "packageManager" in app/package.json with sed (no jq/node) and pass the release tag to the official installer (bash -s bun-v<version>; $1 is the tag in src/runtime/cli/install.sh of oven-sh/bun). The toolbox keeps a Bun that already has that version.

Test: runs toolbox.sh and the docs' Debian line from a copy, with stubs for toolbox, curl, bash and bun (nothing downloaded or installed), and checks the installer command line.

Before (origin/main):

FAIL no Bun yet: installs packageManager's (1.4.4): got [bash  <- curl -fsSL https://bun.sh/install], want [bash -s bun-v1.4.4 <- curl -fsSL https://bun.sh/install]
FAIL other Bun (1.2.9): installs 1.4.4: got [nothing], want [bash -s bun-v1.4.4 <- curl -fsSL https://bun.sh/install]
ok   Bun 1.4.4 there: nothing to do: (nothing)
FAIL packageManager without a space (bun@1.3.0): got [bash  <- curl -fsSL https://bun.sh/install], want [bash -s bun-v1.3.0 <- curl -fsSL https://bun.sh/install]
FAIL docs, Debian line (bun@1.3.0): got [bash  <- curl -fsSL https://bun.sh/install], want [bash -s bun-v1.3.0 <- curl -fsSL https://bun.sh/install]
exit 1

After:

ok   no Bun yet: installs packageManager's (1.4.4): bash -s bun-v1.4.4 <- curl -fsSL https://bun.sh/install
ok   other Bun (1.2.9): installs 1.4.4: bash -s bun-v1.4.4 <- curl -fsSL https://bun.sh/install
ok   Bun 1.4.4 there: nothing to do: (nothing)
ok   packageManager without a space (bun@1.3.0): bash -s bun-v1.3.0 <- curl -fsSL https://bun.sh/install
ok   docs, Debian line (bun@1.3.0): bash -s bun-v1.3.0 <- curl -fsSL https://bun.sh/install
exit 0
