`spacetime start` - Port available when in doubt (#5564)

# Description of Changes

If we fail to check port availability, move forward as though it's
available, to avoid being entirely borked in environments where we do
not have permission to check port availability.

Closes #5556.

# API and ABI breaking changes

None really. Technically technically an API change for the CLI, but not
in a way that causes meaningful pain.

# Expected complexity level and risk

# Testing

Existing CI only. I have not tested this specific branch.

[bfops/release/candidate/v2.6.1-hotfix3]: durability: Make local `His…

…tory` truly read-only (#5497)

`Commitlog::open` may perform repairs, which can be catastrophic if
access is not externally guaranteed to be mutually exclusive.

Instead of allowing to view `Commitlog` as a `History`, implement a
`LocalHistory` that is guaranteed to be read-only.

1.5

Should pass existing tests.

[release/candidate/v2.6.1-hotfix1]: Incorporate a generation value in…

…to database program bootstrap (#5471)

# Description of Changes

HostController now captures the database row’s bootstrap generation when
a database is launched and exposes it through `BootstrapCompletion` so
cloud can report bootstrap completion per generation after the initial
`st_module` write is durable. This generation value is needed to ensure
database resets can identify bootstrap completion events from before and
after the reset.
