Fix reply to single model silently skipping AI response

[sidharthmirch]

Fixes the bug where replying to a single model in the reply window saves the user message but never generates an AI response.

Root cause

ChatInput.tsx:363 was passing replyToModelConfig?.modelId (e.g. "anthropic::claude-sonnet-4-5") to populateBlock. This flows into fetchModelConfigById which queries WHERE model_configs.id = ? — expecting a UUID primary key. The mismatch caused it to return null, and usePopulateToolsBlock returned { skipped: true } silently.

Fix

One-line change: replyToModelConfig?.modelId → replyToModelConfig?.id

Test plan

• Open a multi-model chat and send a message
• Click Reply on one model's response to open a reply window
• Type a message and send it
• Confirm the model generates a response (previously it would silently do nothing)
• Verify normal (non-reply) chat still works as before

Pull request overview

This PR fixes the “reply to a single model silently skips AI response” bug by ensuring reply flows pass a model config primary key (config id) into block population. In addition, it introduces a broader set of model-management and UX features (visibility, profiles, defaults, minimize/reorder columns), plus supporting persistence/migrations and build/docs updates.

Changes:

• Fix reply-to-single-model by passing/storing model config IDs (not provider model IDs) through the reply + populate pipeline.
• Add model visibility filtering, model/prompt profiles, defaults management, and per-project default prompt profiles; update settings + pickers accordingly.
• Add multi-model UX improvements (minimize/reorder columns, retry handling/tool-disable heuristics), title-generation model selection, and supporting migrations/build docs/workflow updates.

The new migrations are not listed in ascending version order (version 144 appears before 143). If the migration runner applies migrations in vector order (rather than sorting by version), this can lead to incorrect application/recording order. Please reorder these entries so migrations are appended in monotonically increasing version order (…142, 143, 144).

useProviderVisibilityMap() creates and returns a new Map instance on every render. Because many callers use this value in useMemo/dependency arrays, this forces unnecessary recomputation even when the underlying data hasn't changed. Consider memoizing the map with useMemo keyed on data (or return the raw array and let callers memoize) so the reference stays stable across renders.

useChatCompareModelConfigs builds visibleConfigs using getFilteredModelConfigs(..., null) (no active model profile). Elsewhere (e.g. ChatCompareSelection.fetchVisibleModelConfigsForSelection and ManageModelsBox) the active model profile is applied, so this can produce an inconsistent state where the current chat selection includes models outside the active profile and the picker UI can't represent them. Consider including the active model profile here as well (or explicitly document that chat compare selection ignores the active profile).

PR title/description states this is a one-line fix for single-model reply (replyToModelConfig?.modelId → replyToModelConfig?.id), but this PR also introduces substantial new functionality (model visibility, model/prompt profiles, minimize/reorder UI, defaults, new migrations, etc.). Please either update the PR description to reflect the full scope or split these unrelated changes into separate PRs to reduce review/rollback risk.
