"Startup snippets" tip describes a feature that doesn't exist (snippet as host Pre-command)

[kipavy]

Problem

docs/terminal/snippets.md:99 (the "Startup snippets" tip) claims:

Set a snippet as the Pre-command on a host (connection form → Advanced) to run it every time you connect.

This capability does not exist in the app today. The host Pre-command (and Post-command) fields accept only an inline command string, which is written verbatim to the shell — there is no snippet picker and no snippet resolution. Verified in the client:

• ConnectionForm.tsx:567-583 — plain single-line inputs, no snippet reference
• client.rs:892 — writer.write_all(format!("{}\n", cmd)) on connect
• session.rs:242/256 — same for post_command on disconnect

So a reader following this tip cannot set a snippet there. (Also note: Post-command runs on disconnect, not connect.)

Options

1. Correct the docs now — reword the tip so it reflects reality (a pre-command is an inline command line you type in; a one-liner from a snippet can be pasted, but snippets aren't selectable there).
2. Keep as-is once the feature ships — the app-side feature request is tracked in Allow a snippet as host Pre/Post command (keep inline support); fix docs mismatch voltius#63 (allow a snippet as pre/post command while keeping inline). If/when that lands, this tip becomes accurate and the two should be closed together.

Recommend doing (1) in the interim regardless, so the published docs don't describe a missing feature.

Suggested interim wording

Startup commands — set a Pre-command on a host (connection form → Advanced) to run a command line every time you connect. (Running a full saved snippet here is tracked in voltius#63.)
