Add 3 opt-in Loki tools (query_logs, list_labels, list_label_values)
that are registered when LOKI_URL is configured. Includes Loki HTTP
client, CLI commands (logs, labels), NixOS module option, formatting,
and tests.

The create_silence tool is a write operation that can suppress alerts.
Disable it by default and require explicit opt-in via --enable-silences
CLI flag (or enableSilences NixOS option) as a safety measure.

Add InstructionsFunc callback to ServerConfig, called during each
initialize handshake to generate dynamic instructions. The lab-monitoring
server uses this to query Alertmanager and include a count of active
non-silenced alerts, so the LLM can proactively inform the user.

New MCP server that queries live Prometheus and Alertmanager HTTP APIs
with 8 tools: list_alerts, get_alert, search_metrics, get_metric_metadata,
query (PromQL), list_targets, list_silences, and create_silence.
Extends the MCP core with ModeCustom and NewGenericServer for servers
that don't require a database. Includes CLI with direct commands
(alerts, query, targets, metrics), NixOS module, and comprehensive
httptest-based tests.
Bumps existing binaries to 0.2.1 due to shared internal/mcp change.

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

Add support for running the MCP server over HTTP with Server-Sent Events
(SSE) using the MCP Streamable HTTP specification, alongside the existing
STDIO transport.
New features:
- Transport abstraction with Transport interface
- HTTP transport with session management
- SSE support for server-initiated notifications
- CORS security with configurable allowed origins
- Optional TLS support
- CLI flags for HTTP configuration (--transport, --http-address, etc.)
- NixOS module options for HTTP transport
The HTTP transport implements:
- POST /mcp: JSON-RPC requests with session management
- GET /mcp: SSE stream for server notifications
- DELETE /mcp: Session termination
- Origin validation (localhost-only by default)

When indexing a revision that already exists, the indexer now returns
early with information about the existing revision instead of re-indexing.
Use the --force flag to re-index an existing revision.

File indexing only adds ~3 seconds to the indexing process, so enable
it by default to make the get_file tool work out of the box.
- MCP index_revision tool now indexes files automatically
- CLI flag changed from --files to --no-files (opt-out)
- Update README examples
