docs: Apply documentation standards across all docs (#49177)

## Summary

Comprehensive remediation of 146 documentation files to align with Zed's
documentation conventions and brand voice guidelines.

## Changes

### YAML Frontmatter
- Added `title` and `description` frontmatter to all docs missing it

### Settings UI Pattern
- Updated 48+ files to show Settings Editor before JSON examples
- Pattern: `Configure X in Settings ({#kb zed::OpenSettings}), or add to
your settings file:`
- Added `([how to edit](./configuring-zed.md#settings-files))` links for
JSON-only settings

### Brand Voice Fixes
- Removed exclamation points (command-palette, key-bindings, repl,
privacy-and-security, etc.)
- Simplified em dash chains to parentheticals (environment,
troubleshooting, agent-panel, etc.)
- Fixed marketing language (yarn.md intro, development/linux.md)

### Terminology Alignment
- `settings UI` -> `Settings Editor`
- `sidebar` -> specific panel names (Project Panel, Collab Panel)
- `directory` -> `folder` in non-technical contexts
- `workspace` -> `project` in non-LSP contexts
- `Command Palette` -> `command palette` (lowercase)

### Callout Standardization
- Converted various callout formats to standard `> **Note:**` pattern

## Related

Depends on conventions established in #49176.

 # Debugging Crashes
 
-When Zed panics or otherwise crashes, Zed sends a message to a sidecar process which inspects the memory of the crashing editor to create a [minidump](https://chromium.googlesource.com/breakpad/breakpad/+/master/docs/getting_started_with_breakpad.md#the-minidump-file-format) file in `~/Library/Logs/Zed` or `$XDG_DATA_HOME/zed/logs`. This minidump can be used to generate backtraces for the stacks of all threads.

You can use this minidump to generate backtraces for all thread stacks.
 
-If you have enabled Zed's telemetry these will be uploaded to us when you restart the app. They end up in a [Slack channel](https://zed-industries.slack.com/archives/C0977J9MA1Y) and in [Sentry](https://zed-dev.sentry.io/issues) (both of which are Zed-staff-only).

+These crash reports include useful data, but they are hard to read without spans or symbol information. You can still analyze them locally by downloading source and an unstripped binary (or separate symbols file) for your Zed release, then running:
 
 ```sh
 zstd -d ~/.local/share/zed/<uuid>.dmp -o minidump.dmp
 minidump-stackwalk minidump.dmp
 ```
 
-Alongside the minidump file in your logs dir, there should be a `<uuid>.json` which contains additional metadata like the panic message, span, and system specs.

 ## Using a Debugger
 
-If you can reproduce the crash consistently, a debugger can be used to inspect the state of the program at the time of the crash, often providing useful insights into the cause of the crash.
