Handlers now accept their actual dependencies directly:
- Root handlers: ModelCache, Broker, context.Context, etc.
- Session handlers: *SessionNode, removeFn, renameFn
- Agent handlers: *agent.Agent, *AgentLog, *SessionNode
Ctl dispatch tables are now per-instance closures built at binding
time rather than package-level vars with generic Hctx.
Also inlined the intermediate internalBinding type — adapt functions
now build fsedsl.Binding directly from raw data.
Removed: Hctx struct, rdwrHandler type, rdwrDispatch func,
bypassBindings helper, processBindings helper, internalBinding type.
Converted the entire 9P namespace spec from progressive Hctx population
to closure capture. Handlers are now closures that capture their
dependencies (session, agent, etc.) at binding time.
Hctx remains as a transitional adapter — handlers still receive it,
but it's constructed per-call from captured state rather than threaded
through the tree. Will be removed in a follow-up once handlers are
converted to use captured state directly.
