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
