Surfaces the assign/milestone mutations end-to-end so they're usable in-app and
by the agent — the rest of #24.
Agent path:
- propose_change tool + system prompt now accept `assignee` (login/null) and
`milestone` (id/null). ProposeChangeArgs + proposalsFor extended: a new
ProposalContext (current assignee/milestone + milestones list) lets a proposal
skip no-ops and label the milestone. ChangeProposal gains an always-present
`summary` (plan is now label-only) — chat-panel, use-chat, and the model
executor render `summary`, so non-label proposals display correctly.
Dialog path:
- Client `listCollaborators()` (prepends the repo owner — /collaborators omits
them, so a solo-owner repo still has an assignable person). New
`gitea:collaborators` bridge. The Adjust dialog gains Assignee + Milestone
pickers (current values from the reconciled backlog); pending assign/remilestone
changes flow through the existing apply path.
Tests: +4 core (assign/milestone proposals with no-op skip; collaborators
owner-prepend + no-double-add). 138 core green; core + desktop typecheck clean;
14 fixture e2e green; live-backlog now drives the pickers on real data.
Fixed stale P2 refs in live-backlog (P2 is shipped → correctly off the runway).

The write path handled only the est/* and p/* label axes. Extend it to the two
mutations dogfooding proved were missing — assignee and milestone — behind one
unified change model:
- IssueChange gains `assign` and `remilestone` kinds. `planIssueChange` is now
typed to LabelChange (the label kinds only); `isLabelChange` narrows, and a new
pure `summarizeChange(change, currentLabels?)` gives one confirm line for ANY
kind (label kinds delegate to describeChange; field writes describe directly).
- GiteaClient gains `setIssueAssignees` / `setIssueMilestone` (PATCH /issues/{n},
returning the updated issue; milestone 0 clears).
- The main `gitea:applyChange` handler branches: label swaps resolve ids +
setIssueLabels as before; field writes call the new client methods. Snapshot
invalidated either way so board + forecast catch up. ApplyChangeResult.plan is
now optional (absent for field writes).
- issue-screen uses summarizeChange for its diff preview.
Tests: +5 covering isLabelChange, and summarizeChange for assign/unassign,
milestone set-by-title / by-id / removal, and label delegation. Full core suite
132 green; core + desktop typecheck clean.
Follow-up (rest of #24): surface assignee/milestone pickers in the Adjust dialog
and extend the agent's propose_change tool so Reginald can propose them too.
