Merge branch 'fix-terminal-viewport-culling-rebased' into nathan

This brings the terminal element's viewport culling in line with the editor
optimization in PR #44995 and the fix in PR #45077.

## Problem

When a terminal is inside a scrollable container (e.g., the Agent Panel
thread view), it would render ALL cells during prepaint, even when the
terminal was entirely outside the viewport. This caused unnecessary CPU
usage when multiple terminal tool outputs existed in the Agent Panel.

## Solution

Calculate the intersection of the terminal's bounds with the current
content_mask (the visible viewport after all parent clipping). If the
intersection has zero area, skip all cell processing entirely.

### Important distinction between content modes:

- **ContentMode::Scrollable**: Cells use the terminal's internal coordinate
  system with negative line numbers for scrollback history. We cannot filter
  cells by screen-space row numbers, so we render all cells when visible.
  The early-exit for zero intersection handles the offscreen case.

- **ContentMode::Inline**: Cells use 0-based line numbers (no scrollback).
  We can filter cells to only those in the visible row range, using the
  same logic that existed before but now extracted into a helper function
  with proper bounds clamping to prevent the hang bug from PR #45077.

## Testing

Added comprehensive unit tests for:
- compute_visible_row_range edge cases
- Cell filtering logic for Inline mode
- Line/i32 comparison behavior

Manually verified:
- Terminal fully visible (no clipping)
- Terminal clipped from top/bottom
- Terminal completely outside viewport (renders nothing)
- Scrollable terminals with scrollback history work correctly

Release Notes:

- Improved Agent Panel performance when terminals are scrolled offscreen.

+# Phase 2: Explore Repository
+
+You are analyzing a codebase to understand its structure before reviewing documentation impact.
+
+## Objective
+Produce a structured overview of the repository to inform subsequent documentation analysis.
+
+## Instructions
+
+1. **Identify Primary Languages and Frameworks**
+   - Scan for Cargo.toml, package.json, or other manifest files
+   - Note the primary language(s) and key dependencies
+
+2. **Map Documentation Structure**
+   - This project uses **mdBook** (https://rust-lang.github.io/mdBook/)
+   - Documentation is in `docs/src/`
+   - Table of contents: `docs/src/SUMMARY.md` (mdBook format: https://rust-lang.github.io/mdBook/format/summary.html)
+   - Style guide: `docs/.rules`
+   - Agent guidelines: `docs/AGENTS.md`
+   - Formatting: Prettier (config in `docs/.prettierrc`)
+
+3. **Identify Build and Tooling**
+   - Note build systems (cargo, npm, etc.)
+   - Identify documentation tooling (mdbook, etc.)
+
+4. **Output Format**

+## Input
+You will receive:
+- List of changed files from the triggering commit/PR

+1. **Categorize Changed Files**
+   - Source code (which crates/modules)
+   - Configuration
+   - Tests
+   - Documentation (already existing)
+   - Other
+
+2. **Analyze Each Change**
+   - Review diffs for files likely to impact documentation
+   - Focus on: public APIs, settings, keybindings, commands, user-visible behavior
+
+3. **Identify What Did NOT Change**
+   - Note stable interfaces or behaviors
+   - Important for avoiding unnecessary documentation updates
+
+4. **Output Format**
+Produce a markdown summary:

+# Phase 4: Plan Documentation Impact
+
+You are determining whether and how documentation should be updated based on code changes.
+
+## Objective
+Produce a structured documentation plan that will guide Phase 5 execution.
+
+## Documentation System
+This is an **mdBook** site (https://rust-lang.github.io/mdBook/):
+- `docs/src/SUMMARY.md` defines book structure per https://rust-lang.github.io/mdBook/format/summary.html
+- If adding new pages, they MUST be added to SUMMARY.md
+- Use `{#kb action::ActionName}` syntax for keybindings (custom preprocessor expands these)
+- Prettier formatting (80 char width) will be applied automatically
+
+## Input
+You will receive:
+- Change analysis from Phase 3
+- Repository structure from Phase 2
+- Documentation guidelines from `docs/AGENTS.md`
+
+## Instructions
+
+1. **Review AGENTS.md**
+   - Load and apply all rules from `docs/AGENTS.md`
+   - Respect scope boundaries (in-scope vs out-of-scope)
+
+2. **Evaluate Documentation Impact**
+   For each behavioral change from Phase 3:
+   - Does existing documentation cover this area?
+   - Is the documentation now inaccurate or incomplete?
+   - Classify per AGENTS.md "Change Classification" section
+
+3. **Identify Specific Updates**
+   For each required update:
+   - Exact file path
+   - Specific section or heading
+   - Type of change (update existing, add new, deprecate)
+   - Description of the change
+
+4. **Flag Uncertainty**
+   Explicitly mark:
+   - Assumptions you're making
+   - Areas where human confirmation is needed
+   - Ambiguous requirements
+
+5. **Output Format**
+Use the exact format specified in `docs/AGENTS.md` Phase 4 section:
+
+```markdown
+## Documentation Impact Assessment
+
+### Summary
+Brief description of code changes analyzed.
+
+### Documentation Updates Required: [Yes/No]
+
+### Planned Changes
+
+#### 1. [File Path]
+- **Section**: [Section name or "New section"]
+- **Change Type**: [Update/Add/Deprecate]
+- **Reason**: Why this change is needed
+- **Description**: What will be added/modified
+
+### Uncertainty Flags
+- [ ] [Description of any assumptions or areas needing confirmation]
+
+### No Changes Needed
+- [List files reviewed but not requiring updates, with brief reason]
+```
+
+## Constraints
+- Read-only: Do not modify any files
+- Conservative: When uncertain, flag for human review rather than planning changes
+- Scoped: Only plan changes that trace directly to code changes from Phase 3
+- No scope expansion: Do not plan "improvements" unrelated to triggering changes
