docs: sync HTTP endpoint table with actual server routes

Remove non-existent /dispatch endpoints (MCP tools, not HTTP),
fix /workflows/{name} split into GET + POST /run, replace
/teams/{name}/status|tasks with /teams/{name}/spawn, correct
/tasks/{id} to /tasks/{team}/{id}, and add missing /runs/*,
/feishu/webhook, and /assistant endpoints.

feat: add dispatch MCP tool for one-step task dispatching

Adds `dispatch` tool to the MCP server (internal/mcp/dispatch_tool.go)
that wraps the existing dispatch package, letting Claude Code dispatch
natural language tasks to an agent team in a single call instead of
manually calling team_create + agent_add + task_create + start_all.

- dispatch tool: takes text, project, channel, callback_url, model
- registerDispatchTool() called in RunServer() alongside other tool groups
- CLAUDE.md updated: 43 → 44 tools, added Dispatch tools section

docs: update README for HTTP REST API and 43 MCP tools

- Add HTTP REST API Server section with full endpoint table
- Update MCP tools count 39/40 → 43 (Config:10 Agent:25 Stats:4 Workflow:4)
- Add codes serve command to commands reference
- Add chatsession/ and httpserver/ to dev structure
- Document httpTokens and httpBind config fields
- Update both English and Chinese READMEs

fix: allow self-update to run on dev builds

refactor: split commands.go into per-command files (closes #18) (#40)

Split the 2354-line monolithic commands.go into 11 focused files:
- version.go: Version vars, RunVersion, RunClaudeUpdate, RunSelfUpdate, checkForUpdates
- select.go: RunSelect, RunClaudeWithConfig, runClaudeInDirectory
- install.go: InstallClaude, installBinary, installShellCompletion, appendCompletionLine
- add.go: RunAdd
- init_cmd.go: RunInit
- start.go: RunStart
- project_cmd.go: RunProject* functions
- profile.go: RunTest, testSingleConfiguration, testAllConfigurations, RunProfileList/Remove
- config_cmd.go: RunConfig*, RunDefaultBehavior*, RunSkipPermissions*, RunTerminal*
- remote_cmd.go: parseSSHAddress, RunRemote* functions
- serve.go: RunServe, RunHTTPServer

No behavior changes. Build and all tests pass.

feat: track API profile per session for per-profile stats (#32) (#38)

- Add Profile field to SessionRecord, populated with config.Default at scan time
- Add ByProfile map to DailyStat for per-profile cost aggregation
- Add ProfileCost struct and TopProfiles to Summary
- Add ProfileBreakdown() aggregator function
- Update Aggregate() to populate ByProfile data
- Add 'profile' view to TUI Stats tab f-key cycle (all→project→model→profile→all)
- Add aggregateByProfile() and rendering in stats_view.go

feat: async task cancellation, task_redirect MCP tool, and /dispatch …

…callback URL

- Refactor daemon to execute tasks in background goroutines, enabling
  external cancellation by polling task file status every 3s. Context
  cancellation sends SIGTERM to the Claude subprocess.

- Add RedirectTask(): cancel a running task and create a replacement
  with updated instructions, inheriting owner/priority/project/workDir.

- Add task_redirect MCP tool (tool count 41→42) for MCP callers to
  cancel and replace running tasks in a single atomic operation.

- Add CallbackURL field to Task; /dispatch endpoint accepts optional
  callback_url and daemon POSTs task result on completion/failure/cancel.

- Add test_progress MCP tool to verify MCP progress notification support.
  Confirmed Claude Code sends progressToken on every tool call.

- Update webhook/hook handlers to support cancelled status
  (task_cancelled event, on_task_cancelled hook).

- Add 9 new tests covering all new functionality.

fix: skip TestGetAdapter when claude CLI is not installed

CI environments don't have claude CLI, causing GetAdapter to fail
with "CLI tool not found". Use t.Skipf instead of t.Fatalf to
gracefully skip the test in such environments.

feat: add team_subscribe MCP tool for blocking notification delivery

Add a new team_subscribe tool that blocks until agent task notifications
arrive for a specific team, replacing the need for shell-based polling
via team_watch. Uses sync.Cond for efficient wake-up instead of
time.Sleep polling.

Changes:
- monitor.go: add notifCond, drainTeamNotifications, subscribeTimeoutOverride
- agent_tools.go: add teamSubscribeHandler with deadline/ctx support
- monitor_e2e_test.go: 3 new tests (receive, timeout, team filtering)
- Update tool count 39 → 40 in CLAUDE.md and README.md

fix: correct garbled character in Chinese README
