fix(permission): require read and shell descriptions

[shabeeth2]

Require a trimmed, nonblank description field for read and shell tool calls in the legacy and Core V2 schemas. The description is propagated to normal and external-directory permission requests. Missing or blank values fail validation before execution or permission prompting.

Changes

• Added description validation to bash and read tool schemas in core
• Propagated descriptions to permission prompts in the TUI
• Updated tests and parameter snapshots
• 24 files changed, 986 insertions, 177 deletions

Verification

• Core read/bash tests: 31 passed
• OpenCode read/shell tests: 111 passed
• Parameter tests: 58 passed
• TUI permission tests: 11 passed
• Focused session prompt test: 1 passed
• \git diff --check: passed

The following comment was made by an LLM, it may be inaccurate:

Based on my search, I found one potentially related PR:

#26419 - fix(opencode): make bash tool description parameter optional
#26419

This PR addresses the bash tool description parameter, while PR #49400 requires descriptions to be nonblank and trimmed. These are related changes to the same tool schema, though #26419 made descriptions optional while #49400 enforces them as required.

All other results are either the current PR itself (#49400) or unrelated PRs about different features (workflows, storage, authentication, etc.).
