Merge origin/main into brennanb2025/fix-pin-duplication

Resolve conflicts from ~1500 commits of main drift: - AppearancePane: take main's refactored section structure; relocate the 'Also show pinned worktrees in their original lists' toggle into AppearanceWindowSidebarSection where main moved the sibling sidebar toggles. - SettingsFormControls: keep main's description-conditional row padding plus the PR's optional className passthrough. - worktree-list-groups.ts: restore main's visiblePinnedRepoIds declaration dropped by the auto-merge (still used by main's external-inbox repo loop). - worktree-list-groups.test.ts: interleaved test blocks reassembled; realign one buildRows call for main's new newExternalWorktreesInboxByRepo parameter. - locale catalogs: keep main's keys, add the pinned-setting strings (all 5). Verified: typecheck:web, localization catalog+coverage, 174 sidebar tests, 57 settings tests, oxlint on touched files — all green.

+# Windows inner-binary signing rehearsal.

+# Why: SignPath cannot deep-sign inside NSIS installers, so shipping signed
+# inner binaries (Orca.exe, node-pty *.node, DLLs — see issue #7785) requires
+# a two-request flow: sign the unpacked PE files first, then build the NSIS
+# installer from the signed tree, then sign the installer. This workflow
+# rehearses that entire flow from a branch, end to end, without publishing
+# anything — so the release pipeline on main is never at risk while we verify.
+#
+# Runs only via manual dispatch. Use the test-signing policy for iteration
+# (auto-approved test certificate) and release-signing to rehearse the
+# production flow (requires manual SignPath approvals). Rehearsed successfully
+# with test-signing (run 28987534795) and release-signing (run 28988432001).

+## Git Binary Compatibility
+
+Orca runs the user's Git binary on native, WSL, and SSH hosts, which may all have different versions. Treat Git 2.25 as the core-workflow baseline and follow [`docs/reference/git-compatibility.md`](./docs/reference/git-compatibility.md).
+
+When adding or changing a Git command:
+
+- Check when every subcommand and option was introduced. For newer behavior, keep a baseline-compatible fallback or degrade safely.
+- Use `GitCapabilityCache` with a narrow unsupported-error predicate so recurring operations do not retry a known-invalid command. Do not rely only on `git --version`; wrappers such as `simple-git` do not remove host-version differences.
+- Scope capability state to the host that executes Git: native, WSL distro, SSH provider, or relay connection. Cover the first fallback, later cached calls, concurrent probes, and relevant host isolation in tests.
+- Keep the real-binary compatibility contract in PR CI current. When adopting a newer Git feature, add its version boundary so the preferred command and fallback both run against representative Git releases.
+- Preserve commands that begin with global Git options such as `-c` before the subcommand, including auto-maintenance suppression used by worktree-create fetches.

+ *
+ * Hard assertions (fail the job):
+ *   - the daemon signals `{ type: 'ready' }` over IPC within the timeout, and
+ *   - it terminates when asked (no hang / zombie).
+ * Best-effort (logged skip, never fails): an end-to-end `ptySpawnHealth` RPC,
