refactor(lockfile): use compact inline table format

[jdx]

Summary

• Remove name field from PlatformInfo (derivable from URL)
• Remove size field from serialization (keep for reading, skip writing)
• Use inline tables for platform entries with dotted keys
• Stop pruning tools not in current toolset - fixes autofix deleting lockfile entries
• Reduces mise.lock from 728 lines to 243 lines (67% reduction)

Before

[[tools.actionlint]]
version = "1.7.9"
backend = "aqua:rhysd/actionlint"

[tools.actionlint.platforms.linux-arm64]
checksum = "sha256:..."
name = "actionlint_1.7.9_linux_arm64.tar.gz"
size = 12345
url = "https://..."

After

[[tools.actionlint]]
version = "1.7.9"
backend = "aqua:rhysd/actionlint"
"platforms.linux-arm64" = { checksum = "sha256:...", url = "https://..."}

Pruning Fix

The update_lockfiles() function was aggressively removing tools from the lockfile if they weren't in the current toolset. This caused:

• Tools added via mise lock but not in mise.toml to get removed
• Previously locked versions (e.g., node 24.6.0 when node = "24" now resolves to 24.11.1) to get removed

The pruning logic has been removed entirely. The lockfile will now only add/update entries, never remove them.

Test plan

• Unit tests pass
• E2E lockfile tests updated and pass
• Backend tests (github, gitlab) updated and pass

Note

Switches lockfile to compact dotted inline platform entries, removes name and size serialization, updates backends accordingly, and stops pruning tools from lockfiles.

• Lockfile:
  • Convert platform data to compact dotted inline tables (e.g., "platforms.linux-x64" = { ... }); formatter rewrites nested platforms tables to inline.
  • PlatformInfo: remove name; stop serializing size (kept in-memory only); update (de)serialization to support inline format and ignore unknown size on write.
  • Update parsing to accept both nested platforms tables and dotted inline keys; keep multi-version [[tools.X]] format.
  • Update lockfile update flow to merge/preserve entries (no pruning of tools; preserve base/env-specific entries across configs).
• Backends:
  • GitHub/GitLab/Aqua/Conda/backends: stop reading/writing name; populate url, url_api, and checksum only; adjust asset resolution and lock info methods.
  • Core backend checksum/size handling retained in-memory; lockfile write omits size.
• Tests/Fixtures:
  • E2E tests updated to assert dotted inline platforms.$PLATFORM keys and absence of size/name.
  • Regenerated mise.lock using new inline platform format with URLs/checksums.

Pull request overview

This PR addresses inconsistent lockfile generation by removing the size field from being written to lockfiles. The size field was only populated during installation but not during mise lock commands, leading to lockfile entries with inconsistent data. The change maintains backward compatibility by allowing existing lockfiles to still read the size field.

Key Changes

• Modified the PlatformInfo struct to skip serializing the size field while maintaining deserialization support
• Commented out the code that writes the size field in the From<PlatformInfo> for toml::Value implementation

[nitpick] The TODO comment spans multiple lines and lacks clarity on ownership and next steps. Consider reformatting as a single-line comment or adding an issue reference for tracking. Example: // TODO(#issue): Add size back when lockfile generation can populate it

Suggested change

	// TODO: Add size back if we find a good way to generate it with `mise lock`
	// Currently size is only available during installation, not during lockfile generation
	#[serde(skip_serializing, default)]
	pub size: Option<u64>,
	// TODO: Add size back when lockfile generation can populate it
	#[serde(skip_serializing, default)]
	pub size: Option<u64>,
	pub size: Option<u64>,

[Copilot]

Commented-out code should typically be removed rather than kept in the codebase. If this needs to be preserved for reference, consider adding a note about why it's kept or link to the same TODO tracking issue mentioned in the struct definition.

Suggested change

	// if let Some(size) = platform_info.size {
	// table.insert("size".to_string(), (size as i64).into());
	// }
