feat: desktop draft welcome presets and /plan-feature command

Add starter preset chips under the composer on the desktop draft welcome
screen (explore, what changed, plan, review). Clicking a chip submits
immediately; prompt chips send a natural-language prompt, command chips
reuse built-in slash commands.

Add a new /plan-feature built-in command, modeled on /workspace-review:
visible + hidden magic prompts that run a guided, batched-question
planning dialogue (investigate the code, ask up to 3 clarifying
questions at a time, surface pitfalls, then produce an implementation
plan). Wired into command autocomplete, the submit handler, the draft
plan chip, and the Magic Prompts settings page, with i18n across all
locales.

+
+Run this as a dialogue, not a one-shot answer.
+
+1. Understand before asking. Once the user describes the idea, first investigate the codebase yourself — read the relevant files, existing patterns, data flow, and constraints. Ground every question in what the code actually shows, not in assumptions.
+
+2. Ask in small batches. Ask at most 3 clarifying questions at a time — a number a person can comfortably answer in one reply. Prefer concrete, decision-oriented questions (option A/B/C, edge cases, scope boundaries) over vague open-ended ones. Number them.
+
+3. Keep going until it is resolved. After each batch of answers, integrate them, do any further code investigation the answers require, then ask the next batch. Continue until there are no unresolved decisions or implementation details left. Do not stop early or start summarizing prematurely.
+
+4. Surface what the user has not considered. Proactively raise edge cases, pitfalls, affected modules, migration/backward-compatibility concerns, and trade-offs the user likely did not think about. Fold these into your questions so the user decides — never silently decide for them.
+
+5. Do not write code or begin implementing during this phase. Planning is for understanding and deciding only.
+
+6. When everything is settled, produce the final implementation plan: a clear, ordered breakdown of the work, the files and areas affected, the decisions that were made (and why), known risks, and any remaining assumptions flagged explicitly. The plan must reflect the user's actual answers — never fill gaps with guesses.
+
+Respond in the same language the user uses.`,
