The `getAgentPrompt` tRPC procedure previously read exclusively from
`.cw/agent-logs/<name>/PROMPT.md`. Once the cleanup-manager removes
that directory, the prompt is gone forever.
Adds a `prompt` text column to the `agents` table and writes the fully
assembled prompt (including workspace layout, inter-agent comms, and
preview sections) to the DB in the same `repository.update()` call
that saves pid/outputFilePath after spawn.
`getAgentPrompt` now reads from DB first (`agent.prompt`) and falls
back to the filesystem only for agents spawned before this change.

Adds exitCode to AgentInfo type and propagates it through all toAgentInfo()
implementations. Enhances getAgent to also return taskName and initiativeName
from their respective repositories. Adds two new filesystem-reading tRPC
procedures for the Agent Details tab: getAgentInputFiles (reads .cw/input/
files with binary detection, 500 KB cap, sorted) and getAgentPrompt (reads
.cw/agent-logs/<name>/PROMPT.md with 1 MB cap and structured ENOENT handling).
