CC hooks stripped to zero for performance

Context

CC UserPromptSubmit hook (okf-prompt-lookup + cavemem) timing out at 60s on every prompt. Blocked entire terminal.

Decision

Settings.json stripped to:

• hooks: {} (empty)
• alwaysThinkingEnabled: false
• autoMemoryEnabled: false
• showThinkingSummaries: false

Removed: cavemem, okf-prompt-lookup, memory-pull, memory-push, mcp-orphan-guard, journal-cc-session-end, oriz-lint-file, rtk PreToolUse.

Rationale

• Hooks add latency on every action
• okf-prompt-lookup fired on every prompt with 60s timeout
• Cavemem/RTK/OKF benefits < startup cost for interactive use

Impact

• Startup: 3.58s → ~1s
• No more UserPromptSubmit blocks
• Skills/knowledge still accessible manually via mcp__foam__ + okf-index-lookup

Reversal path

Re-add specific hook if measurable value > latency cost. Prefer async hooks over sync.
