Prior to this change the check would happen before we would know if the
file read was successful.

- Define custom key types (testStringKey, testBoolKey, testIntKey)
- Replace string literals with typed constants
- Fixes SA1029: should not use built-in type string as key for value

- Add runSubAgent and runSubAgentWithOptions methods to coordinator
- Simplify agent_tool.go from 106 to 60 lines (43.4% reduction)
- Simplify agentic_fetch_tool.go from 235 to 200 lines (14.9% reduction)
- Eliminate 81 lines of duplicated session management code
- Support custom session setup via callback for special cases
- Improve error handling with proper error wrapping
- Add updateParentSessionCost helper for consistent cost propagation

- Introduce generic getContextValue helper function to eliminate code duplication
- Reduce code from 75 to 56 lines (25.3% reduction)
- Simplify Get*FromContext functions from ~13 lines to 2 lines each
- Add comprehensive test coverage (18 test cases) for context functions
- Maintain backward compatibility with existing API

hasRootMarkers used fsext.Glob which triggered a full recursive fastwalk
of the working directory with no gitignore filtering. In large JS
monorepos this walked millions of files in node_modules, causing 800%
CPU usage. Root markers are simple filenames (go.mod, package.json,
*.gpr, etc.) that only need a single-directory check.

- Remove dead client from map when initialization fails to allow retry
- Use client's cwd field instead of os.Getwd() in openKeyConfigFiles
- Fix slog key-value pair in HandleServerMessage error logging
- Remove redundant hardcoded timeout in WaitForServerReady

The `callback` field was `nil` when the app returned early before
`SetCallback` was called, causing a segfault in `startServer`.

Some MCP servers advertise resources capability but don't implement
resources/list, causing the entire MCP client to fail. This change
handles JSON-RPC error code -32601 gracefully by marking resources
as unavailable instead of failing.

Fixes #2227

- Add missing return after error send in RunNonInteractive goroutine
- Use context.WithoutCancel for shutdown to preserve tracing context
- Use strings.EqualFold for case-insensitive model matching
- Preserve LSP ConnectedAt across state transitions

One of our indirect dependencies switched to "MIT-0". This is even more
permissive than MIT, so totally valid for us.

- Fix misleading error message: report "small model provider not configured"
  instead of "large" when the small model provider is missing
- Fix error handling order in view tool: check readTextFile error before
  UTF-8 validation to avoid validating partial/empty content
- Fix MCP tool filtering: move "MCP not allowed" log into correct branch
  and break after tool is added to prevent duplicate additions

When building the small model provider, we were incorrectly passing
largeModelCfg instead of smallModelCfg to buildProvider. This caused
isAnthropicThinking to check the wrong model config, preventing the
small model from enabling Anthropic thinking mode even when configured.

Fixes #2141

They changed the `/models` endpoint so it actually validates the API key
header if given.
