[feat] Linear status reconciliation view

[Sph3ricalPeter]

Priority: P2
Effort: ~2–3 days
AI required: No
Depends on: Persistent commit↔issue index

A view showing mismatches between local git state and Linear issue states. The kind of thing nobody can build because nobody else sees both sides.

Scope — surfaces these conditions:

• Issues marked Done in Linear with unpushed local commits referencing them
• Issues assigned to user, not Done, with no commits referencing them (forgotten work)
• Branches with issue IDs whose issue was closed by someone else
• Issues with commits across multiple branches (potential confusion)
• Local branches for issues that have been deleted/archived in Linear

Acceptance criteria:

• Dedicated view accessible from Linear panel or command palette
• Each mismatch type clearly labeled with suggested action
• Bulk actions where sensible (e.g., delete branches for archived issues)
• No false positives from stale cache — verify before flagging

Hi @Sph3ricalPeter! I'd love to work on this issue.
I've gone through the scope and acceptance criteria — the reconciliation view makes a lot of sense as a VS Code panel that cross-references the local git state with Linear issue statuses. I'm comfortable working across both the Rust backend (for git/index queries) and the React/TypeScript frontend (for rendering mismatch types with suggested actions).
A few quick clarifying questions before I start:

Is the persistent commit↔issue index (#depends-on) already merged, or should I build against a WIP branch?
Do you have a preferred UI pattern for the mismatch list — e.g., tree view grouped by mismatch type, or a flat list?
For bulk actions, should they go through the command palette or inline buttons in the view?

Happy to take this on if you can assign it to me. Thanks!
