Prevents CLAUDE.md walk-up through parent directories by passing --bare
to every Claude CLI invocation, and explicitly injects the workspace
CLAUDE.md via --append-system-prompt-file so agent identity is isolated.
Adds fake-claude fixture and integration test to verify flags are present.

Introduces src/runtime/env.ts with a pure sanitizedEnv() function that
strips DISCORD_BOT_TOKEN, DISCORD_CLIENT_SECRET, DISCORD_PUBLIC_KEY, and
all keys matching /^(DISCLAW_SECRET_|SECRET_|TOKEN_|API_KEY_?)/i before
passing the environment to spawned Claude Code child processes. Adds
optional env_blocklist field to DisclawConfig. Runner now passes
DISCLAW_AGENT_NAME and respects the blocklist.
