fix(tui): last table row missing in markdown rendering

[mocksoul]

Bug

The last row of markdown tables is always missing after message streaming completes.

Reproduction

1. Enable OPENCODE_EXPERIMENTAL_MARKDOWN=true
2. Ask the AI to output a markdown table with 3+ data rows
3. After streaming completes, the last row is not visible

Root cause

Two issues work together:

1. opencode: TextPart passes streaming={true} unconditionally to <markdown> and <code> elements — even for completed messages
2. opentui: During streaming, the last table row is skipped (rows.slice(0, -1)) as potentially incomplete. When streaming changes to false, updateBlocks() skips the table because tokenRaw hasn't changed — the missing row is never added back

Fix

• opencode: Derive streaming from message.time.completed — fix(tui): stop streaming markdown/code after message completes #13854
• opentui: Use clearCache() on streaming: true→false transition — fix(markdown): rebuild table when streaming ends opentui#696
