language: Change signature of initialization_options_schema (#45937)

This makes this take the LSP adapter delegate instead of the binary
itself.

Despite us passing `LanguageServerBinaryOptions` with `allow_download:
false`, extensions would still try to download the binary because it was
never implemented for these to respect that. This would cause us to try
to download all langauge servers provided by extensions when opening a
settings file and/or requesting the JSON schema for that.

This PR fixes this by passing the LSP adapter delegate instead, so the
few language servers which actually want to have the binary for
resolving the initialization options can decide on this by themselves.
With that, we no longer download all language servers for the schema
request

+# 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**
+Produce a JSON summary:
+
+```json
+{
+  "primary_language": "Rust",
+  "frameworks": ["GPUI"],
+  "documentation": {
+    "system": "mdBook",
+    "location": "docs/src/",

+# Phase 3: Analyze Changes
+
+You are analyzing code changes to understand their nature and scope.
+
+## Objective
+Produce a clear, neutral summary of what changed in the codebase.
+
+## Input
+You will receive:
+- List of changed files from the triggering commit/PR
+- Repository structure from Phase 2
+
+## Instructions
+
+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:
+
+```markdown
+## Change Analysis
+
+### Changed Files Summary
+| Category | Files | Impact Level |
+| --- | --- | --- |
+| Source - [crate] | file1.rs, file2.rs | High/Medium/Low |
+| Settings | settings.json | Medium |
+| Tests | test_*.rs | None |
+
+### Behavioral Changes
+- **[Feature/Area]**: Description of what changed from user perspective
+- **[Feature/Area]**: Description...
+
+### Unchanged Areas
+- [Area]: Confirmed no changes to [specific behavior]
+
+### Files Requiring Deeper Review
+- `path/to/file.rs`: Reason for deeper review
+```
+
+## Constraints
+- Read-only: Do not modify any files
+- Neutral tone: Describe what changed, not whether it's good/bad
+- Do not propose documentation changes yet

+# 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

+# Phase 5: Apply Documentation Plan
+
+You are executing a pre-approved documentation plan for an **mdBook** documentation site.
+
+## Objective
+Implement exactly the changes specified in the documentation plan from Phase 4.
+
+## Documentation System
+- **mdBook**: https://rust-lang.github.io/mdBook/
+- **SUMMARY.md**: Follows mdBook format (https://rust-lang.github.io/mdBook/format/summary.html)
+- **Prettier**: Will be run automatically after this phase (80 char line width)
+- **Custom preprocessor**: Use `{#kb action::ActionName}` for keybindings instead of hardcoding
+
+## Input
+You will receive:
+- Documentation plan from Phase 4
+- Documentation guidelines from `docs/AGENTS.md`
+- Style rules from `docs/.rules`
+
+## Instructions
+
+1. **Validate Plan**
+   - Confirm all planned files are within scope per AGENTS.md
+   - Verify no out-of-scope files are targeted
+
+2. **Execute Each Planned Change**
+   For each item in "Planned Changes":
+   - Navigate to the specified file
+   - Locate the specified section
+   - Apply the described change
+   - Follow style rules from `docs/.rules`
+
+3. **Style Compliance**
+   Every edit must follow `docs/.rules`:
+   - Second person, present tense
+   - No hedging words ("simply", "just", "easily")
+   - Proper keybinding format (`Cmd+Shift+P`)
+   - Settings Editor first, JSON second
+   - Correct terminology (folder not directory, etc.)
+
+4. **Preserve Context**
+   - Maintain surrounding content structure
+   - Keep consistent heading levels
+   - Preserve existing cross-references
+
+## Constraints
+- Execute ONLY changes listed in the plan
+- Do not discover new documentation targets
+- Do not make stylistic improvements outside planned sections
+- Do not expand scope beyond what Phase 4 specified
+- If a planned change cannot be applied (file missing, section not found), skip and note it
+
+## Output
+After applying changes, output a summary:
+
+```markdown
+## Applied Changes
+
+### Successfully Applied
+- `path/to/file.md`: [Brief description of change]
+
+### Skipped (Could Not Apply)
+- `path/to/file.md`: [Reason - e.g., "Section not found"]
+
+### Warnings
+- [Any issues encountered during application]

+
+### Review Notes
+- Items reviewers should pay special attention to
+- Any uncertainty flags from Phase 4 that were addressed
+- Assumptions made during documentation
+```
+
+3. **Add Context for Reviewers**
+   - Highlight any changes that might be controversial
+   - Note if any planned changes were skipped and why
+   - Flag areas where reviewer expertise is especially needed
+
+## Output Format
+The summary should be suitable for:
+- PR description body
+- Commit message (condensed version)
+- Team communication
+
+## Constraints
