fix(list): discover descendant local libraries

[runsonmypc]

Repositories that separate OpenSpec libraries by product currently hide descendant work when openspec list runs at the repository root. This fix discovers the selected local library plus valid descendants for changes and specs, then groups terminal output by relative library path with totals, empty states, aligned columns, optional terminal colors, and narrow-terminal wrapping. The CLI uses the terminal’s existing background; the captures use a near-black palette.

Closes #2008.

• Reuses existing item parsers, task/status logic, sorting, and root-selection rules. Discovery supports legacy layouts, prunes dependencies/build/cache/worktree/planning directories, skips directory symlinks, and deduplicates physical roots.
• --store and project store pointers stay scoped to the selected store. Other commands retain their selection and mutation behavior.
• Single-library JSON retains its shape. Aggregated arrays add library ownership and roots metadata; unreadable/malformed libraries report actionable diagnostics while readable libraries remain visible.
• Includes CLI help/reference updates, the list specification, and a patch changeset.

Validation: node build.js, tsc --noEmit, eslint src/ (the contribution guide’s build/type/lint scripts), CLI list-spec validation, whitespace checks, and all 6,314 tests across 215 files passed. Coverage includes root plus nested libraries, no-root discovery, legacy/single/empty libraries, duplicate names, exclusions/symlinks, sorting, specs/clean JSON, store/product scope, unreadable/malformed libraries, and narrow output.

After the color update: build/type/lint checks and 61 focused listing tests passed; ANSI-stripped output matches --no-color, and JSON stays free of styling.

Actual source-built CLI captures below use temporary fixtures with fictional directory and item names. The PNGs faithfully render captured stdout. Capture text and details are hosted on a separate artifact branch; the code diff contains no screenshots or demo fixtures.

Summary by CodeRabbit

• New Features
  • openspec list discovers changes or specs in the selected local library and valid descendant libraries. Text results are grouped by library, with per-library empty states; aggregated JSON identifies each result’s library and includes root metadata.
  • Explicitly selected stores remain limited to that store. Changes are sorted by recency by default or by name with --sort name within each library.
• Bug Fixes
  • Readable libraries remain listed when another library is unreadable or malformed. A diagnostic is reported and the command exits with a nonzero status.
• Documentation
  • Updated CLI guidance with discovery scope, supported layouts, output formats, and error behavior.

📝 Walkthrough

Walkthrough

The list command now discovers eligible descendant OpenSpec libraries for local listings. It groups text results by library and aggregates JSON results with library ownership. Explicitly selected stores remain limited to one store.

Changes

Recursive local listing

Layer / File(s)	Summary
Listing root and library discovery openspec/specs/cli-list/spec.md, src/cli/index.ts, src/core/list-discovery.ts, src/core/root-selection.ts	The CLI resolves an implicit local listing root when applicable and enables recursive listing for local roots. Discovery identifies eligible descendant libraries, skips excluded directories and symlinks, and reports diagnostics. Explicit store selection remains scoped to one store.
Per-library listing and aggregated results src/core/list.ts, test/core/list-discovery.test.ts, test/commands/store-root-selection.test.ts, test/cli-e2e/view-store-resolution.test.ts, docs/cli.md, .changeset/*	List results are emitted per library in text output or combined in JSON. Recursive output includes library ownership and roots; diagnostics set a nonzero exit code while readable libraries remain listed. Tests and documentation cover output, sorting, discovery, and store scope.

Before / after behavior

• observed — Modified behavior in docs/cli.md: Replaces the brief description of listing project changes with documentation for multi-library listing. It specifies root-based or directory-based discovery, --store scope, supported layouts, excluded directories, and no symlink traversal. It also describes text output and JSON aggregation, including per-entry library labels, relative roots and canonical paths, distinct duplicate names, and library-scoped failures and nested-change warnings.
• observed — Modified behavior in docs/cli.md: Replaces the single-library text-output example with a temporary-repository excerpt showing four libraries and four changes, with entries under the root library.
• observed — Modified behavior in openspec/specs/cli-list/spec.md: Adds requirements for discovering the selected local library and valid descendants in both modes, with stated exclusions, legacy layout support, and physical-root deduplication. Specifies root-first stable path ordering, per-library totals and empty states, store-only scope when explicitly or pointer-selected, aggregated JSON ownership and root metadata while preserving single-library JSON, and nonzero failure reporting for malformed or unreadable libraries while retaining successfully read libraries.
• observed — Modified behavior in openspec/specs/cli-list/spec.md: Changes the recursive local listing empty-state requirement from a single “No active changes found” message to a per-library “No active changes” state.
