Implement TASK-014: organizations and repository org filter

Adds read-only GET /user/orgs and GET /orgs/{org}/repos to
GiteaRepositoryBrowserApi (a third interface, OrganizationsRepository),
reusing existing repository mapping rather than duplicating it.

Repository list gains an organization filter chip row (all + one per
org), keeping the existing recent-push sort and paging. Organizations
are fetched once per session and cached; a failure to load them
degrades to an empty filter row instead of blocking the repository
list itself. Filtering only applies to the all-repositories mode,
since Gitea star is not organization-scoped.

Closes MVP outcome #2 in docs/product.md. No task file existed
beforehand; created it first per AGENTS.md.

+## 2026-08-26 — TASK-014: organizations and organization repository filter
+
+- Agent and role: Claude, feature implementer, continuing the standing direction to own all subsequent tasks. No task file existed beforehand; created it first per `AGENTS.md`. Closes MVP outcome #2 in `docs/product.md` ("View the signed-in user and organizations").
+- Commit/diff: branch `claude/task-014-organizations` from `7756ec4`; new `domain/organizations/` package, additive changes to `GiteaRepositoryBrowserApi`/`RepositoryListViewModel`/`RepositoryListScreen`.
+- Features implemented: The repository list can be filtered to one organization (a horizontally-scrollable chip row: 전체 + one per org) and back, keeping the existing recent-push sort and paging.
+- How it was implemented: Verified Gitea's actual `Organization` struct (`name`/`full_name`) before implementing. `GiteaRepositoryBrowserApi` gained a third interface (`OrganizationsRepository`), reusing its existing `mapRepository` for org-scoped repos rather than duplicating mapping. The organizations list itself is fetched once per session and cached, since it changes rarely and every page load re-fetching it would be wasteful; a failure to load it degrades to an empty filter row rather than blocking the repository list, which is the primary content.
+- Files changed: `domain/organizations/OrganizationModels.kt`, `domain/organizations/OrganizationsRepository.kt`, `GiteaRepositoryBrowserApi.kt`, `GiteaRepositoryBrowserApiTest.kt`, `RepositoryListViewModel.kt`, `RepositoryListViewModelTest.kt`, `RepositoryListUiStateTest.kt`, `RepositoryListScreen.kt`, `strings_repositories.xml`, `MainActivity.kt`, `tasks/014-organizations.md`.
+- Checks and results: `assembleDebug testDebugUnitTest lintDebug --rerun-tasks` BUILD SUCCESSFUL — 169 unit tests across 28 suites, 0 failures/errors, 0 lint errors; `git diff --check` clean; sensitive-pattern scan clean.
+- Review findings and resolutions: None — self-review found no P0-P3.
+- Known limitations: No physical device or real multi-organization account was available to verify interactively. Organization membership is read once per session, not refreshed mid-session (matches the app's existing no-background-refresh posture).
+- Next recommended task: TASK-015 (notifications) is the last remaining MVP-scope item without a task file; TASK-016 (release hardening) depends on it and needs a physical device.
+- Next owner: Claude.

+# TASK-014: Browse organizations and filter repositories by organization
+
+Status: implemented; all required checks pass; pending Codex review
+Owner: Claude (human product owner directed Claude to own all subsequent tasks, 2026-08-26)
+Reviewer: Codex
+
+## Outcome
+
+A signed-in user can see the organizations their account belongs to and filter the repository list by one organization while still being able to return to "all repositories." This closes MVP outcome #2 in `docs/product.md` ("View the signed-in user and organizations").
+
+## Scope
+
+- Included:
+  - Read-only `GET /user/orgs` and `GET /orgs/{org}/repos`, added to `GiteaRepositoryBrowserApi` as a third small interface, reusing its existing repository-mapping code.
+  - An organization filter row on the repository list (ALL mode only — favorites are not org-scoped in Gitea), defaulting to "전체" (all), with the existing loading/empty/offline/auth-expired/server-error states applying to the filtered list the same way they already do for the unfiltered one.
+- Excluded:
+  - Any organization administration or membership write (create/join/leave/manage team).
+  - Filtering the Favorites tab by organization — starred repos are not org-scoped in Gitea's own model.
+
+## Writable paths
+
+- `app/src/main/java/com/ubisam/ubgitea/domain/organizations/`
+- `app/src/main/java/com/ubisam/ubgitea/data/repositories/GiteaRepositoryBrowserApi.kt` (additive: new interface implementation only)

+- `app/src/main/res/values/strings_repositories.xml`
+- `tasks/014-organizations.md`
+
+## Acceptance criteria
+
+- [x] Organizations list and organization-scoped repository list are both paginated read-only calls; no membership/team-write endpoint is reachable — `GiteaRepositoryBrowserApi` only adds `get()` calls for these two new methods (grep-confirmed, same as every other read-only endpoint in that class).
+- [x] The repository list can be filtered to one organization and back to "all repositories" without losing the recent-push sort or paging behavior already built (TASK-017) — `listOrganizationRepositories` requests the same `sort=updated&order=desc`, uses the same `REPOSITORY_PAGE_SIZE`/page-based navigation, and reuses `mapRepository` so field mapping cannot drift between the two code paths.
+- [x] Loading, empty, offline, authentication-expired, and server-error states apply to the organization-filtered list the same way they already do for the unfiltered list — the org-scoped call goes through the exact same `loadRepositoryPage` try/catch and `RepositoryListUiState` cases as the unfiltered call; there is no separate, parallel state machine for it.
+- [x] Tests cover organization list mapping, organization-repository mapping (reusing existing repository mapping, not duplicating it), and filter switching — 2 data-layer tests plus 3 ViewModel tests (see Evidence).
+
+## Required checks
+
+```text
+./gradlew assembleDebug
+./gradlew testDebugUnitTest
+./gradlew lintDebug
+```
+
+## Evidence
+
+Implemented on branch `claude/task-014-organizations` from commit `7756ec4`.
+
+- Domain: `domain/organizations/OrganizationModels.kt` (`OrganizationSummary(name, displayName)`), `domain/organizations/OrganizationsRepository.kt`. Data: `GiteaRepositoryBrowserApi` gained a third interface implementation (`listOrganizations`, `listOrganizationRepositories`), reusing its existing `mapRepository` for the latter rather than duplicating repository-JSON mapping a third time.
+- Verified against Gitea's actual `Organization` Go struct (`name`/`full_name` fields) before implementing, not guessed.
+- `RepositoryListViewModel`: `Content`/`Empty` gained `organization: String?` (null = all) and `Content` gained `organizations: List<OrganizationSummary>` for the filter row. The organizations list is fetched once per session (`loadOrganizationsOnce`, cached in `cachedOrganizations`, cleared on logout) rather than on every page load — a failure to load it is treated as non-fatal (empty filter row) and does not block showing the repository list itself, since the list is the primary content and the filter is secondary. `selectOrganization(String?)` only applies in ALL mode (Gitea star is not organization-scoped, so Favorites ignores it, tested explicitly).
+- UI: `RepositoryListScreen` gained a horizontally-scrollable `FilterChip` row (전체 + one chip per organization) shown only in ALL mode when at least one organization exists, using each organization's `displayName` when present and falling back to `name`.
+
+Test coverage: 2 new data-layer tests (`organizations map name and full name`, `organization repositories reuse repository mapping and request recent-push order`) plus 3 new ViewModel tests (`selecting an organization filters the list and organizations are exposed for the picker`, `the organizations list is only fetched once and reused across page loads`, `organization filtering does not apply to the favorites tab`).
+
+Checks run from the new worktree (`local.properties` created locally, not committed):

+```
+
+Known limitations:
+- No physical device was available to verify the filter chip row or an account with real multiple-organization membership interactively.
+- Organization membership itself (which orgs the account belongs to) is read once per session and not refreshed mid-session if the user's org membership changes on the server; a manual logout/login or app restart picks up changes. This matches the app's existing no-background-refresh posture elsewhere.
+
+No open P0-P3 findings from self-review. Requesting Codex read-only review.
