* fix(ui): follow scroll when at bottom

This change attempt to completely fix the agent scroll issue when at
bottom. It should follow the agent when the follow flag is set.

* fix(ui): make sure we select the last item when at bottom

Fix rangesOverlap() to treat LSP ranges as half-open intervals [start, end)
per the specification. Adjacent edits where one range ends where another
begins are no longer incorrectly rejected as overlapping.

Catwalk v0.25.0 release: https://github.com/charmbracelet/catwalk/releases/tag/v0.25.0

This updates `vertexai.json` provider definition to include `gemini-3.1-*` and `claude-*-4.6`.

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
