feat(chat): natural-language tool titles, past-tense completion, and smooth agent-group narration

[waleedlatif1]

Summary

• Show past-tense tool titles once a tool call completes successfully ("Querying logs" → "Queried logs") via a leading-gerund verb map applied to the resolved title; failed/cancelled calls keep the attempted-action wording, and the workspace_file live-title path gets the same rewrite
• Add natural gerund titles for ~50 tools that previously fell through to robotic Title Case ("Deploy Api" → "Deploying API"), and make humanizeToolName keep acronym casing (MCP, API, OAuth, URL, ID, AI)
• Smooth agent-group narration rows with useSmoothText (word-by-word paced reveal on the live tail row), matching top-level text
• Render inline markdown (bold, italic, code, label as label) in narration rows instead of leaking raw syntax
• Tone narration rows with --text-muted (drop the opacity-60 stack on --text-secondary)
• Insert a space at the seam when consecutive thinking/text blocks glue together ("triggered it.The failing" → "triggered it. The failing")

Type of Change

• Improvement

Testing

Unit tests added for past-tense rewrites, acronym casing, gerund title coverage, inline markdown rendering, and text-seam joins; full message-content suite passing (50 tests), typecheck clean

PR Summary

Low Risk
Presentation-layer changes in chat message parsing and rendering with broad unit test coverage; no auth, data, or API contract changes.

Overview
Improves copilot chat presentation: tool labels get gerund titles for many tools, acronym-aware humanization, and past-tense rewrites on success (via getToolCompletedTitle in toToolData and the workspace_file live-title path). Agent-group narration uses useSmoothText on the live tail, a lightweight renderInlineMarkdown helper, and --text-muted styling.

Parsing merges thinking/text with a guarded space at channel seams only. Tool rows in groups drop per-tool status icons and show text-only titles with shimmer while executing.

Tests cover title rewrites, inline markdown, and seam joining.
