paseo-bot[bot]andAlexander Adam 0ed57187a9 Keep fork owners in Gitea and Forgejo checkout names (#6829)
* fix(gitea): prefix fork PR branches with the owner

Two forks with the same branch name (say patch-1) ended up on the same
local branch. The gitea service had no buildPrLocalBranchName or
defaultCheckoutRefs, github has both.

getPullRequestCheckoutTarget also fell back to refs/heads/<name> on
origin for fork PRs. Thats the base repo's branch, not the fork's, so
a failed refs/pull fetch checked out the wrong branch without an error.

fixes #3515

* refactor(forge): share fork branch naming with github

moved the owner normalizer and the branch name builder to
utils/change-request-checkout.ts, gitea and github both use it.

github changes a bit: a fork PR with an unknown or unusable owner (eg
deleted fork) now gets pr-N/<branch> instead of the bare branch name,
which could collide with a local branch the same way #3515 did.

* fix(gitea): PRs from a deleted fork are still cross repo

the API drops head.repo once the fork is gone, we read that as a same
repo PR and fetched refs/heads/<name> from origin

* fix(gitea): handle AGit PRs and deleted head branches

neither has a branch on origin. forgejo reports refs/pull/N/head as
head.ref for both, so skip the refs/heads fallback and dont track
origin.

also try refs/pull/N/head on upstream for clones where origin is your
fork, like github does. that list lives in the shared util now.

* test: resolver harness uses the real branch helper

plus deleted forks and same repo PRs without an origin branch

* fix(gitea): collapse pull-ref-only heads to pr-N in local branch names

buildForkLocalBranchName still used the raw headRef even when it was
just the pull ref (refs/pull/N/head), which agit prs and deleted head
branches report as their headRefName. that gave local branches literal
names like refs/heads/refs/pull/3/head.

* fix(gitea): surface hasHeadBranch on the pr checkout target

resolveForkCheckoutFacts already knew whether a pr had a real head
branch (agit flow, or head.ref == the pull ref both mean no). now that
signal reaches buildPrLocalBranchName so worktree names and local
branches stop being named after the raw pull ref.

covers same-repo, fork with owner known, and deleted fork all with no
real head branch. added an end to end gitea-service test plus resolver
cases since the worktree slug follows localBranchName too.

* refactor(forge): one head ref kind on the checkout target

hasOriginHeadBranch and hasHeadBranch could describe contradictory
states (cross-repo checkout claiming an origin head branch). collapse
both into headRefKind: "branch" | "pull-ref" and derive origin
tracking in the resolver instead of storing it separately.

* fix(worktrees): avoid branch namespace conflicts in fork checkouts

Fork owner prefixes can name an existing branch as a parent, which Git rejects even when the full proposed name is unused. Allocate names against parent and child refs, suffixing the conflicting segment while preserving existing branches and fetched commits.

* test(worktrees): make fork fixture line endings deterministic

Windows Git converts the fixture checkout to CRLF when core.autocrlf is enabled. Set the repository fixture to preserve its written LF bytes so the content assertion checks the fetched patch on every platform. Reproduced the failure locally with inherited core.autocrlf=true and verified the corrected setup against that same configuration.
