fix: resolve Obsidian marketplace review findings

[chhoumann]

Resolve the automated marketplace review failures for PodNotes 2.20.2 by adopting the supported Obsidian APIs directly instead of preserving compatibility shims for older hosts.

This removes vault-wide note enumeration in favor of inspecting only the expected folder, migrates settings to the declarative and searchable settings API, replaces deprecated DOM/settings/deletion APIs, removes unnecessary assertions, and normalizes promise rejection reasons through one shared helper. Episode downloads now use the bounded binary-append path guaranteed by the new compatibility floor.

manifest.json now requires Obsidian 1.13.0. Published versions.json history is intentionally unchanged. Clipboard access also remains intentional because the user-invoked universal-link command copies its result to the clipboard.

Verification completed:

• exact Obsidian marketplace ESLint rules
• npm run lint
• npm run format:check
• npm run typecheck
• npm run build
• npm run test -- --run - 1,152 tests across 78 files
• uv run --with-requirements docs/requirements.txt mkdocs build -f docs/mkdocs.yml -d site
• real Obsidian 1.13.7 runtime - 19 E2E tests, including settings search/export/import, ranged downloads and Local Files rendering, renamed-note discovery, clipboard sharing, and async rejection normalization
• final runtime read-back reported no notices or captured errors

Focused review areas are the declarative settings render lifecycle and the raised minimum Obsidian version that lets the download path rely on appendBinary without a fallback.

Preserve probe validation errors

When the initial response exceeds the 2 GiB limit or advertises an oversized total, probeAndFetchFirstChunk intentionally throws a descriptive Error, but this catch passes it to downloadRequestError, which replaces every non-NetworkError with the generic “Failed to download episode.” Users therefore lose the actionable size-limit explanation that this path previously surfaced; preserve existing Error instances or only translate actual network failures.

Add the displayed setting names to the search index

Because the tab exposes one declarative definition, Obsidian can search only its name and this alias list rather than the Setting controls created inside render. These aliases say “Import preferences” and “Export preferences,” while the displayed controls are named “Import settings” and “Export settings,” and “Include API keys” is omitted entirely, so searching for those visible labels produces no PodNotes result. Index every displayed control name, including these three.
