Package search now prioritizes results in this order:
1. Exact pname match
2. Exact attr_path match
3. pname starts with query
4. attr_path starts with query
5. FTS ranking (bm25 for SQLite, ts_rank for PostgreSQL)
This ensures searching for "git" returns the "git" package first,
rather than packages that merely mention "git" in their description.
Also update CLAUDE.md to clarify using `nix run` instead of
`go build -o` for testing binaries.

Add a new nixpkgs-search CLI that combines NixOS options search with
Nix package search functionality. This provides two MCP servers from
a single binary:
- `nixpkgs-search options serve` for NixOS options
- `nixpkgs-search packages serve` for Nix packages
Key changes:
- Add packages table to database schema (version 3)
- Add Package type and search methods to database layer
- Create internal/packages/ with indexer and parser for nix-env JSON
- Add MCP server mode (options/packages) with separate tool sets
- Add package handlers: search_packages, get_package
- Create cmd/nixpkgs-search with combined indexing support
- Update flake.nix with nixpkgs-search package (now default)
- Bump version to 0.2.0
The index command can index both options and packages together, or
use --no-packages/--no-options flags for partial indexing.

Add //nolint:errcheck comments to intentionally unchecked error returns:
- defer X.Close() calls: errors from closing read-only resources, rows
after iteration, files, response bodies, and gzip readers are not
actionable and don't affect correctness
- defer tx.Rollback(): standard Go pattern where rollback after
successful commit returns an error, which is expected behavior
- defer stmt.Close(): statements are closed with their transactions
- Cleanup operations: DeleteRevision on failure and os.RemoveAll for
temp directories are best-effort cleanup
- HTTP response encoding: if JSON encoding fails at response time,
there's nothing useful we can do
- Test/benchmark code: unchecked errors in test setup/cleanup where
failures will surface through test assertions

The argNum variable tracks parameter positions but the final value is
unused. Added explicit acknowledgment to silence the linter.

- testFileRange: test GetFileWithRange with various offset/limit values
- testDeclarationsWithMetadata: test file metadata in declarations
- Verify byte_size and line_count are computed correctly
- Test edge cases: offset beyond EOF, non-indexed files

When searching for option paths like "services.nginx", use name-based
LIKE matching instead of full-text search. This ensures the results
are options that start with the query, not random options that mention
the term somewhere in their description.
- Path queries (containing dots): use LIKE for name prefix matching
- Text queries (no dots): use FTS for full-text search on name+description

Wrap search queries in double quotes for FTS5 literal matching.
This prevents dots, colons, and other special characters from
being interpreted as FTS5 operators.
Fixes: "fts5: syntax error near '.'" when searching for option
paths like "services.nginx".

Tests searching with dots, colons, hyphens, and parentheses.
Currently fails on SQLite due to FTS5 syntax interpretation.
